Definitions:

Ribosomes

Molecular machines within cells where proteins are synthesized, following the instructions encoded in RNA.

mRNA

Messenger RNA, which carries genetic information from DNA to the ribosome, where it serves as a template for protein synthesis.

AUG Codon

The mRNA codon that signals the start of protein synthesis, typically coding for the amino acid methionine in eukaryotes and a modified methionine in prokaryotes.

Translation

The process by which the sequence of bases in mRNA is used to direct the sequential addition of amino acids, building polypeptide chains in protein synthesis.
