DNA stands for 'Deoxyribonucelic Acid' which is a type of nucleic acid and encodes the genetic information, used in development and functioning, of all living organisms.
The building block of a nucleic acid is a nucleotide.
The building block of a nucleic acid is a nucleotide.
Nucelotides have three components:
There are four bases; Adenine, Thymine, Guanine and Cytosine A and T are always paired which means G and C are always paired. These pairs are called 'complementary'. More of these bases will be shown in DNA structure page. |
