Question

Quizplus · Accepted Answer

A gene is defined as a segment of DNA that carries the instructions for one polypeptide chain. This means that a gene contains the information needed to code for a specific protein or part of a protein. Genes are made up of nucleotide sequences and can be transcribed into RNA and then translated into a specific amino acid sequence, which ultimately determines the function of the protein.
