A natural unit of hereditary material that is the physical basis for the transmission of the characteristics of living organisms from one generation to another. The basic genetic material is fundamentally the same in all living organisms. It consists of deoxyribonucleic acid (DNA) in most organisms and ribonucleic acid (RNA) in certain viruses, and is usually associated in a linear arrangement that constitutes part of the chromosome.
