   Oct 27, 2020 · Definition. A gene is an extremely specific sequence of nucleotide monomers that has the ability to completely or partially control the expression of one or more traits in every type of living organism. Genes are formed from deoxyribonucleic acid ( DNA) and, in the case of some viruses, ribonucleic acid (RNA) polymers.

   Genes are pieces of hereditary material that are passed from parents to offspring. Genes are part of cell structures called chromosomes. In multicellular organisms, chromosomes are found in the nucleus of the cell. Each of these chromosomes contains one, long molecule of DNA, or d eoxyribo n ucleic a cid.
