Answer:A gene is a short section of a DNA
Explanation: A gene is the fundamental unit of inheritance or hereditary in living organisms. A gene is the DNA segment that codes the information needed to produce an RNA or a protein. Some DNA molecules have short segments that do not code for amino acid sequence of a polypeptide product. These non translational or non coding sequences are called intervening sequences or introns. DNAs also contain coding segments which are called genes.
