Deoxyribonucleic acid and ribonucleic acid are two chemical substances involved in transmitting genetic information from parent to offspring. It was known early into the 20th century that chromosomes, the genetic material of cells, contained DNA. In 1944, Oswald T. Avery, Colin M. MacLeod, and Maclyn McCarty concluded that DNA was the basic genetic component of chromosomes. Later, RNA would be proven to regulate protein synthesis. (Miller, 139) DNA is the genetic material found in most viruses and …

…new polynucleotide chain. The new DNA strand stays attached to the old one through the hydrogen bonds, and together they form a new DNA double helix molecule. (Heath, 119) (Miller, 144-145) As mentioned before, DNA molecules are involved in a process called protein synthesis. Without RNA, this process could not be completed. RNA is the genetic material of some viruses. RNA molecules are like DNA. They have a long chain of macromolecules made up of nucleotides.
