My band Ambiguous Toad covers The Ramones "Blitzkrieg Bop" with our own twist. This was done for a school project, and it was for fun, and somewhat comedic on the vocals ;)

Directed in 1971 by Robert Alan Weiss for the Department of Chemistry of Stanford University and imprinted with the "free love" aura of the period, this short film continues to be shown in biology class today. It has since spawn a series of similar funny attempts at vulgarizing protein synthesis. Narrated by Paul Berg, 1980 Nobel prize for Chemistry.

Ribosome (in blue, gold) makes cell proteins from amino acids delivered by tRNAs (orange, green, purple) and EF-Tu (red), and is a popular target for antibiotics research. A method for capturing ribosome in action is shown; the method reveals movement of a protein (blue, curly) into the ribosome. Visit here for more information: http://www.ks.uiuc.edu/Research/mdff/

RNA is synthesized from DNA, and enters the ribosome where protein translation and synthesis occurs.

I know the animation and photo quality aren't all that great, but it took a while. I made it with JPEG video, a stop motion animation program and I edited it in Windows Movie Maker. It is 15 frames per second and 341 pictures. This video shows transcription of DNA to RNA and translation of RNA to a polypeptide. Here is a slightly more detailed explanation of what is happening because a few things had to be cut: The DNA polymerase (not shown in movie) unzips the DNA. Then the RNA forms, by matching each guanine (G) of the DNA to RNA's cytosine (C) and vice versa; and matching each thymine (T) to adenine (A); and each A to uracil (U). In the movie, T is red, C is brown, G is blue, A is yellow, and U is green. The movie doesn't show this, but the RNA is made by matching each nucleotide one at a time, instead of coming in fully formed as the movie depicts. The enzyme called RNA polymerase is what catalyzes this process, but that also isn't shown in the movie. The DNA goes back together in helix form and the mRNA (messenger RNA, which was just made) moves to the ribosome, an organelle. The ribosome is made up of protein and RNA called rRNA (ribosomal RNA). This is where translation begins. Only two codons (a section of RNA with three nucleotides) can fit in the ribosome at a time. The tRNA (transfer RNA), which are the brown crosses with nucleotides, come into the ribosome. The nucleotides on the bottom of the tRNA, called anti-codons, match the codons of the mRNA. Each tRNA is attached to a specific amino acid, which are the colored balls in the video. The type of amino acid is based on the codon on the mRNA that the tRNA matches. The codons in this video code for Valine, Aspartate, Threonine, Histidine, Tyrosine, and Phenylalanine. The last codon doesn't have a matching tRNA because it is a stop codon which signals for the translation process to stop. These amino acids bond through dehydration synthesis as the process continues to form a polypeptide, thus making protein.

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.

The changes in the electrostatic potential of the 70S ribosome occurring during the ratchet-like motion [1,2]. Potential was obtained by solving the Poisson-Boltzmann equation with the Adaptive Poisson-Boltzmann Solver [3], for various backbone structures of the ribosome derived from normal mode analysis.

In the translation process, interpretation of genetic codes in form of codon along mRNA would create a particular protein. The translator is the transfer RNA (tRNA) which has three nucleoide (anticodon) specific for each type of amino acid. The anticodon bond to the complementary codon of the mRNA and transfering amino acids from cytoplasm to ribosome.

Information Flow in the Cell By Wesley Jacobs, Lindsey Bernstein, and Stuart Yochem The Information flow in the cell beings with a message outside the nucleus that tells it "we need amino acids." This message begins a complex set of actions that will produce amino acid production. The first step is replication. It occurs in the nucleus during cell division and cytokinesis. Replication results in two identical strands of DNA. The second step is Transcription, which also occurs in the nucleus. A portion of the DNA molecule is copied onto a single strand of RNA. In this step DNA is the substrate molecule and RNA is the product. The third and final step is Translation. This is the most complicated step and occurs in the ribosome. The RNA leaves the nucleus and travels to the ribosome where its nitrogenous bases are read. Three nitrogenous bases are called a codon, and each codon codes for one amino acid. This process underlies all proteins and protein function.

DNA in our body contains genetic information that is used for the development of other cells like RNA molecules and proteins. The nitrogenous bases on the DNA code for and correspond to amino acids. DNA replicates itself during replication, which occurs in the nucleus of the cell during cell division. The next step for protein production is transcription in which parts of DNA are transcribed into RNA with the help of the enzyme RNA synthase. The final step occurs outside of the nucleus in which the single strand of RNA moves through the cell cytoplasm and reaches the ribosome. The ribosome reads the sequence of nitrogenous bases and produces amino acids. Each amino acid is produced individually and then are attached to each other through dehydration synthesis until they form an adequate polypeptide chain. The polypeptide chain then goes on to affect the phenotype of the individual and the process from DNA to phenotype is completed.
