2 Chromosome
Recent studies suggest that genes on chromosome two may play an important role in human intelligence.
Human chromosome 2 is unique to the human lineage in being the product of a head-to-head fusion of two intermediate-sized ancestral chromosomes.

2 Chromosome is the
second largest human chromosome. It represents almost
8% of DNA in cells.
People normally have two copies of this chromosome as all other non-sex
chromosomes. Chromosome two spans
about 243 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 1,888 genes in this chromosome.
