Best Answer: A gene encodes a protein. A gene is a sequence of codon pairs that is contained on a chromosome (strand of DNA). The gene is transcribed to a piece of m-RNA, which is then used in the production of the given protein in the ribosomes. This is the classical view. In reality the genetic machinery is a lot more complex.
