Mrna translation (advanced)

The job of the mRNA is to carry the gene's message from the DNA out of the nucleus to a ribosome for production of the particular protein that this gene codes for. Originally created for DNA Interactive ( www.dnai.org ). TRANSCRIPT The job of this mRNA is to carry the genes message from the DNA out of the nuceus to a ribosome for production of the particular protein that this gene codes for. There can be several million ribosomes in a typical eukaryotic cell these complex catalytic machines use the mrna copy of the genetic information to assemble amino acid building blokes into the three dimensional proteins that are essential for life. Lets see how it works. The ribosome is composed of one large and one small sub-unit that assemble around the messenger RNA, which then passes through the ribosome like a computer tape. The amino acid building blocks (that's the small glowing red molecules) are carried into the ribosome attached to specific transfer RNAs. That's the larger green molecules also referred to as tRNA. The small sub-unit of the ribosome positions the mRNA so that it can be read in groups of three letters known as a codon. Each codon on the mRNA matches a corresponding anti-codon on the base of a transfer RNA molecule.The larger sub-unit of the ribosome removes each amino acid and join it onto the growing protein chain. As the mRNA is ratcheted through the ribosome, the mRNA sequence is translated into an amino acid sequence. There are three locations inside the ...

Biochemistry 101- dna translation (protein synthesis- part 2)

This video explains DNA translation, the second major step in how cells synthesize proteins from DNA. If you missed the video on DNA transcription, the first major step in this process, or just need a recap, here's the link: www.youtube.com This is sort of an educational video to bridge the communication gap between me and some of my subs. I understand that I can often forget that not everyone is familiar with some of the jargon I throw around, and often, it's not easy to follow along with some of the stuff I talk about, especially in my more genetics heavy videos. This is one of the educational videos I use in the background of some of my videos, but I've added my own commentary, so that, hopefully, it's easier for layfolk to follow along. Hopefully, though, this bridges some of the translation gap in a way, and as always, I hope it's more educational than it is confusing..., my inner philosophical Darwinist also hopes you enjoy it, too.

Roy parker part 1: mrna localization, translation and degradation

www.ibioseminars.org Part 1 The control of mRNA production and function is a key aspect of the regulation of gene expression. In the first part of this lecture, I will discuss how in eukaryotic cells, the control of mRNA localization, translation and degradation in the cytoplasm allow for the proper regulation of the amount, duration, and location of protein production. The basic mechanisms of these processes are understood and reveal that the mechanisms of localization, translation, and degradation are interconnected. The unique properties of each mRNA are dictated by its intrinsic interactions with cellular machines, as well as its complement of mRNA specific RNA binding proteins and miRNAs. Strikingly, mRNPs are dynamic and can be modulated by protein modifications as well as by modification of the mRNA itself, thereby providing a diversity of targets for the regulation of mRNA function in response to extracellular signals.

For details, see ecampus.oregonstate.edu Download Metabolic Melodies at www.davincipress.com Related courses include BB 350 - oregonstate.edu BB 450 - oregonstate.edu BB 100 - oregonstate.edu Highlights Translation (continued) 1. Eukaryotic translation is mechanistically similar to prokaryotic translation. Differences include ribosomes (40S vs 30S and 60S vs 50S), rRNAs (28S, 18S, 5.8S, and 5S), mRNAs (cap at 5' end and polyA at 3' end, both involved in translation), and lack of formyl group on initiator tRNA's methionine. 2. Other translational differences in eukaryotes relate to the structure of eukaryotic cells. Proteins destined to leave the cytoplasm have a signal sequence, consisting of a stretch of hydrophobic amino acids near their amino terminus. 3. When the signal sequence emerges from the ribosome during translation, it is recognized by the signal recognition particle (SRP), which takes the entire ribosome/mRNA/polypeptide complex to the endoplasmic reticulum. There it interacts with the SRP receptor and in the process it links the ribosome with the emerging polypeptide sequence to the translocon. 4. The polypeptide passes through the translocon channel as it is being made and when the signal sequence completely exits the translocon, a signal peptidase clips ...

Beyond the nuclear pore: from mrna export to translation

Air date: Tuesday, May 03, 2011, 3:00:00 PM Timedisplayed is Eastern Time, Washington DC Local Category: Wednesday Afternoon Lectures Description: The highly selective exchange of proteins and RNA between the nucleus and cytoplasm is essential for cell function, and precisely regulated during cell division, differentiation and death. Many aspects of this process are poorly understood and have direct impacts on human disease. This lecture will have three objectives. One, it will provide background on current models for messenger RNA export from the nucleus to the cytoplasm, and points for key cellular regulation of gene expression. Second, the lecture documents the discovery of essential factors for coupling mRNA export and translation in the budding yeast and cell culture models. Finally, an overall goal is to reveal pathophysiological impacts on development from the study of mRNA export factors in the zebrafish model and human disease linkage analysis. This work provides a direct illustration of how discoveries from the analysis of single cell machineries are required for understanding multicellular organism development and pathophysiology.

A general overview of translation & protein trafficking

Translation is the third stage of protein biosynthesis (part of the overall process of gene expression). In translation, messenger RNA (mRNA) produced by transcription is decoded by the ribosome to produce a specific amino acid chain, or polypeptide, that will later fold into an active protein. In Bacteria, translation occurs in the cell's cytoplasm, where the large and small subunits of the ribosome are located, and bind to the mRNA. In Eukaryotes, translation occurs across the membrane of the endoplasmic reticulum. The ribosome facilitates decoding by inducing the binding of tRNAs with complementary anticodon sequences to that of the mRNA. The tRNAs carry specific amino acids that are chained together into a polypeptide as the mRNA passes through and is "read" by the ribosome in a fashion reminiscent to that of a stock ticker and ticker tape.

Roy parker part 2:p-bodies and the mrna cycle

www.ibioseminars.org In the second part of this lecture, I will provide an overview of why the regulation of translation and mRNA degradation is an important aspect of the control of gene expression in eukaryotic cells. In addition to the translating pool of mRNAs associated with polysomes, recent experiments have identified P-bodies and stress granules as specific cytoplasmic compartments wherein untranslated mRNAs accumulate. In addition to mRNAs, P-bodies tend to contain translation repressors and mRNA degradative enzymes, while stress granules reflect mRNAs in association with some translation initiation factors and RNA binding proteins. P-bodies and stress granules interact and suggest a dynamic process wherein eukaryotic mRNAs remodel their interacting proteins and enter and exit translation, thereby affecting the control of mRNAs in the cytoplasm. We are interested in defining the mechanisms by which P-bodies and stress granules assemble and how cells regulate the movement of mRNAs between these different biochemical and cell biological compartments. Several approaches will be described including biochemical and genetic analyses of known proteins modulating these events, as well as the identification of new factors affecting P-body and stress granule formation and function.

Protein synthesis, translation (1)

Protein Synthesis, Translation Translation - the process of converting the mRNA codon sequences into an amino acid polypeptide chain. 1. Initiation - A ribosome attatches to the mRNA and starts to code at the FMet codon (usualy AUG, sometimes GUG or UUG). 2. Elongation - tRNA brings the corresponding amino acid to each codon as the ribosome moves down the mRNA strand. 3. Termination - Reading of the final mRNA codon (aka the STOP codon), which ends the sythesis of the peptide chain and releases it. Category: Education Length: 00:01:42 Tags: Translation health .

Gene transcription

Gene transcription/translation is the process by which a cell creates a protein. An enzyme, RNA polymerase II, physically moves along the DNA strand on the chromatin where the gene is located and reads the nucleotide sequence to create a complementary RNA molecule. The RNA molecule is modified inside the nucleus before it exports into the cytosol. An extension of As are added to the 3' end, and modified Gs are added to the 5' end of the RNA molecule. The extensions allow the RNA molecule to exit nucleus, they prevent degradation by exonucleases of the RNA that codes for the protein, and they help the RNA find and bind to a ribosome. In the cytoplasm, the mRNA molecule is translateted by tRNA molecules with the help of a ribosome. Specific tRNAs with a specific amino acid attached to each one bind to their specific set of three nucleotide bases (a codon) on the RNA molecule within the ribosome. As the ribosome moves along the RNA molecule, different tRNAs enter the ribosome and leave their corresponding amino acid when bound to their designated codon. The amino acids form peptide bonds with one another as the amino acid sequence grows, and a protein is formed. The protein is then modified to further determine its function. The addition of biochemical functional groups, or the cleavage of polypeptides upon activation of the protein are common post-translational modifications. This song is about transcription.

For more information about online courses go to ecampus.oregonstate.edu for the rest of the courses see www.youtube.com 1. In contrast to prokaryotic mRNAs, eukaryotic mRNAs are extensively modified. Modifications include * Addition of a 5'-5' cap of a methyl guanosine to protect from degradation * Addition of a poly-A tail at the 3' end under the control of the sequence AAUAAA near the end of the mRNA (also to protect from degradation) * Editing - modification of bases chemically, such as was described in class for the Apo-B proteins * Splicing - removal of introns between exons. 2. Splicing is a modification to eukaryotic mRNAs that occurs in the middle of the mRNA. Splicing also occurs to tRNAs and rRNAs in eukaryotes. 3. Splicing involves removal of internal sequences from RNA followed by joining of ends. The removed sequences are called introns. The segments that make it into the final RNA are called exons. 4. The only sequences common to all spliced RNAs are a GU sequence at the 5' end of the intron and an AG at the 3' end of the intron. A third sequence - an A residue surrounded by pyrimidines also is common. 5. Protein/RNA complexes called snRNPs mediate the splicing process in higher eukaryotes. snRNPs contain small nuclear RNAs (snRNAs) and proteins. 6.

This editing process is called splicing. It involves removing non-coding regions called "introns,",leaving only the protein coding "exons." In the cell the introns are removed by special enzymes which recognize specific sequences, these enzymes cut and rejoin the coding regions for translation into protein.

A third modification to eukaryotic mRNAs that occurs is called editing. In editing, a base is chemically changed or added to an existing mRNA. Trypanosomes are unusual in inserting the base 'U' in multiple places in many mRNAs. Doing so is essential to getting the code right for making many of their proteins. 2. A more common editing modification that occurs in human cells is that involved with the Apo B-100 / Apo B-48 protein. Both proteins are coded by the same gene. (Note that I got the two proteins backwards in the lecture. What follows is correct) This lipoprotein is found in chylomicrons (Apo B-48) and liver cells (Apo B-100). Liver cells lack an RNA editing enzyme that intestinal cells have. The editing enzyme converts a C in a CAA sequence in the coding region of the gene to a U, making the stop codon UAA. 3.

DVD Description Our DNA DVD looks first at the structure of DNA before going on to describe how DNA carries out its four major functions: the storage of information; the replication of information; creating slight changes in the information through mutations that forces of natural selection act upon; and the translating of information into the proteins that define an individual. During this discussion students are introduced to: point mutations; insertions and deletions; the genetic code; transfer, messenger, and ribosomal RNA; and the process of replication and translation.

Understanding the missense variant in your family by claire green.m4v

This extends from the podcast 'Determining if a missense variant is the cause of disease' and explains how if a variant is found to be pathogenic/disease-causing, this may translate into a disease state. It describes how a variation in the gene sequence affects protein formation, consequently causing a disease to develop, depending on the function of the protein and/or the effect of the gene change on the protein.
