How many base pairs of DNA represent the haploid human genom

How many base pairs of DNA represent the haploid human genome? How many base pairs of DNA represent the haploid chimpanzee genome? Assume the similarity between human and chimpanzee genomes is 97.5%. Based on 97.5% similarity how many base pairs do the chimpanzee and human genomes differ by?

Solution

The haploid human genome occupies a total of 3.2 billion DNA base pairs. On the other hand chimp genome contains 3.8 base pairs. It would be about 75-80 million base pair differences.
