Chromosomes 02

These 6 billion odd base pairs are split amongst 46 chromosomes. Each person gets 2 pairs of chromosomes, 23 from each parent, to total 46 chromosomes per human cell. A chromosome is the largest form of a DNA molecule, with a large sequence of DNA codes, of differing lengths, usually hundreds of millions of base pairs in each chromosome. chromosomes are independent molecules of DNA, with the typical double-helix, a start and end, but no cycles. chromosomes are physically large enough to be seen on high power microscopes.
