The total length of the human genome is over 3 billion base pairs. The genome is organized into 22 paired chromosomes, plus the X chromosome (one in males, two in females) and, in males only, one Y chromosome. These are all large linear DNA molecules contained within the cell nucleus.
1 Length of one nucleotide pair in a DNA helix: 3.4 angstroms. 2  Average number of nucleotide pairs in a single human DNA molecule: 1.5 x 10^8. 3  Estimated total number of nucleotide pairs in a human cell: 6 x 10^9. 4  The average size of a human cell is 10 micrometers. Estimated total number of nucleotide pairs in a human cell: 6 x 10^9. 2  The average size of a human cell is 10 micrometers. 3  The average size of the nucleus in a human cell is 5 micrometers. 4  1 angstrom equals 0.0000000001 meters. 5  10 billion angstroms equals 1 meter.
