MacLeod, and Maclyn McCarty concluded that deoxyribonucleic acid was the basic transmissible component of chromosomes. Later, RNA would be proven to regulate protein synthesis. (Miller, 139) desoxyribonucleic acid is the genetic material found in most viruses and in all cellular organisms. Some viruses do not flim-flam DNA, but contain RNA instead.
Depending on the organism, most DNA is found within a single chromosome like bacteria, or in several chromosomes like most other donjon things. (Heath, 110) DNA can also be found outside of chromosomes. It can be found in cell organelles such(prenominal) as plasmids in bacteria, also in chloroplasts in plants, and mitochondria in plants and animals.
