The Protein Synthesis Machinery
Protein synthesis, or translation of mRNA into protein, occurs with the help of ribosomes, tRNAs, and aminoacyl tRNA synthetases.

The Mechanism of Protein Synthesis
Protein synthesis involves building a peptide chain using tRNAs to add amino acids and mRNA as a blueprint for the specific sequence.

Protein Folding, Modification, and Targeting
In order to function, proteins must fold into the correct three-dimensional shape, and be targeted to the correct part of the cell.
