Definitions:

Transcription

The process by which the genetic information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA).

mRNA

Messenger RNA, a type of RNA that is transcribed from DNA and carries instructions for synthesizing proteins to the ribosomes.

Ribosome

Ribosomes are molecular machines within cells that synthesize proteins by translating messenger RNA into polypeptide chains, essential for all cellular functions.

Polypeptide Chain

A long, continuous, and unbranched chain of amino acids linked by peptide bonds that forms part of the structure of proteins.
