The Astonishing Length of Human DNA #DNAmarvel #DNAlength #DNAsimilarity #DNAdiversity #DNAevolution #DNAspec | Lorena Sparks

The diploid human genome comprises 6.4 x 109 bp and fits into a nucleus that is 6 μm in diameter. 1. If base pairs occur at intervals of 0.34 nm along the DNA helix, what is the length of DNA in a human cell?2. If the diameter of the DNA helix is 2.4 nm, what fraction of the volume of the nucleus is occupied by DNA? Please explain both of the questions briefly.
