Study Notes

Translation is the process of converting genetic information into functional proteins.
This process is orchestrated by a macromolecular ribonucleoprotein machine called the ribosome.
Transfer RNA (tRNA) is used to translate the nucleotide sequence into an amino acid sequence.
Amino acyl tRNA synthetase enzymes catalyze the loading of the amino acid onto the appropriate tRNA species.
During translation, tRNAs walk along an mRNA in the 5' to 3' direction and sequentially recognize consecutive three nucleotide codons.
The ribosome has binding sites for three different tRNAs: P site, A site, and E site.
The initiation phase of translation consists of the small subunit of the ribosome working with various initiation factors to identify the starting AUG codon.
The elongation phase of translation consists of iterated rounds of amino acid addition and can be broken down into three basic steps: tRNA selection, peptide bond formation, and translocation.
Stop codons are recognized by protein factors known as release factors, which catalyze a hydrolytic reaction that results in the termination of protein synthesis.
The final step in protein synthesis is recycling, which promotes the dissociation of the large and small subunits of the ribosome and the release of the remaining mRNA and tRNA components.
