About Protein Synthesis

Here is a worthwhile article about protein synthesis from BioSolutions. Here is a part of the post:

"Protein translation involves the transfer of information from the mRNA into a peptide, composed of amino acids. This process is mediated by the ribosome, with the adaptation of the RNA sequence into amino acids mediated by transfer RNA. Numerous initation and elongation factors also play a role.

Translation requires a lot of energy, with the hydrolysis of approximately 4 NTP --> NDP per amino acid added. (This includes the aminoacylation of the tRNA. Thus, gene expression is highly regulated to ensure that only proteins that are required are translated.

Translation involves 3 processes: initiation, elongation, and termination."
