c. 124 million
A diploid cell contains 62 million H2A molecules. On DNA replication, these H2A molecules would double i.e become 124 million.
The human genome comprises just over 3.1 billion base pairs. Assuming average nucleosome spacing throughout the...
The diploid human genome comprises 6.4 × 10 9 bp and fits into a nucleus that is 6 μm in diameter. (a) If base pairs occur at intervals of 0.34 nm along the DNA helix, what is the length of DNA in a human cell? (b) If the diameter of the DNA helix is 2.4 nm, what fraction of the volume of the nucleus is occupied by DNA? [Volume of a sphere is (4/3)πr 3 and volume of ...
