3.16 DNA and Genetic information

There are four different types of bases: adenine (A) with thymine (T) and cystosine (C) with guanine (G).

The bases are used to holds the double helix together in the molecules. Base pair is the pairing between
adenine - thymine / guanine - cytosine to held the double helix together.

Bases order have a sequence ....
A C T G A A C C A G = GENE

Genes is equal to the number and order of bases.
