Protein Functions in the Body

Protein synthesis: an epic on the cellular level
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.

What Is DNA?


The process of DNA replication, and protein synthesis through transcription and translation


Transcription and Translation


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 cod
on), which ends the sythesis of the peptide chain and releases it.
