A gene (def) is a segment of DNA that codes for a functional product (mRNA, tRNA, or rRNA). Since the vast majority of genes are transcribed into mRNA and mRNA is subsequently translated into polypeptides or proteins, most genes code for protein synthesis. gene (def) is a segment of DNA that codes for a functional product (mRNA, tRNA, or rRNA).

Transcription is the name given to the formation of RNA molecules from an open DNA chain used as a template. Translation is the creation of polypeptides (amino acids bound in sequence) and therefore of proteins based on information encoded in the mRNA molecule.
