WebbDuring protein synthesis, ribosomes bind to a molecule of messenger RNA (mRNA) that carries the genetic code for the protein being synthesized. The mRNA molecule is read in a process called translation, and the ribosomes synthesize the protein by adding amino acids to the growing protein chain in a specific sequence determined by the genetic code.
