Question

the number of nucleotide base pairs in the haploid set of human chromosomes ​

Answer 1

Answer:

3 billion

The diploid human genome is thus composed of 46 DNA molecules of 24 distinct types. Because human chromosomes exist in pairs that are almost identical, only 3 billion nucleotide pairs (the haploid genome) need to be sequenced to gain complete information concerning a representative human genome.

Answer 2

Answer:

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. Chromosome lengths were estimated by multiplying the number of base pairs by 0.34 nanometers, the distance between base pairs in the DNA double helix. The chromosomes size ranges from 45 to 275 Mb, making the total genome size of 3286 Mb (=3.3 x10

9

bp). Thus the haploid content which is 3.3 x10

9

base pairs
