Definitions:

Leader Sequences

Short sequences of amino acids at the beginning of the synthesis of a protein that signal where in the cell it should be localized.

Ribosomes

Cellular structures responsible for protein synthesis, found in both eukaryotic and prokaryotic cells.

Translation

The conversion of information provided by mRNA into a specific sequence of amino acids in a polypeptide chain; process also requires transfer RNA and ribosomes.

Aminoacyl-tRNA Synthetases

Enzymes that play a crucial role in protein synthesis by attaching the appropriate amino acid to its corresponding transfer RNA (tRNA).
