Desoxyribonucleic Acid (DNA)

Desoxyribonucleic acid (DNA) stores the genetic information for almost all organisms.


It consists of single strands made up of bases (adenine, cytosine, thymine and guanine), sugar units and phosphate units. The strands are held together by hydrogen bonds.

In DNA, adenine and thymine and cytosine and guanine are paired. This enables the formation of hydrogen bonds.
