About Nucleotides

Nucleotides join together in a polymerisation reaction to form DNA.

A nucleotide is made of three components

There are 4 nucleotide bases:

The nucleotides are arranged in complementary pairs. Adenine and Thymine pair up on opposite sides of the DNA strand. The same is true for Cytosine and Guanine. When the strand is pulled into two pieces this allows the DNA to make two exact copies of itself. So if one side of the strand has the code AAAACCCTTG then the other will have the code TTTTGGGAAC.
