(DNA) is a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses. DNA is anucleic acid; alongside proteins and carbohydrates, nucleic acids compose the three major macromolecules essential for all known forms of life.<ref>[http://en.wikipedia.org/wiki/DNA DNA, Wikipedia]</ref> | (DNA) is a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses.

==DNA, RNA and Proteins== | |||
All living beings are reliant on three main molecules for essentially all of their biological functions. These molecules are [[DNA, RNA and Proteins]]. The two strands of [[DNA]] run in opposite directions to each other and are therefore adjacent to each other (anti-parallel). It is the sequence of these four nitrogen bases along the backbone that encodes biological information. Under the genetic code, RNA strands are translated to specify the sequence of amino acids within proteins. These RNA strands are initially created using DNA strands as a template in a process called transcription. Without [[DNA, RNA and Proteins]], no biological life would exist on earth. | |||
