DNA (Deoxyribonucleic acid)
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.
