7 Chromosome
represents more than 5% of the total DNA in cells. People normally have
two copies of this chromosome as all other non-sex chromosomes. Chromosome seven
spans about 159 million base pairs. Base Pairs are two molecules
(nucleotides) on opposite DNA strands that are connected. Adenine (A) forms a
base pair with thymine (T), as does guanine (G) with cytosine (C) in DNA. Base pairs is how DNA is measured.
There are about 1,452 genes in this chromosome.
