Exercise 8

Calculate the number of nucleosomes in a human diploid cell
There is one nucleosome for every 200 bp of eukaryotic DNA. How many nucleosomes are in a diploid human cell Nucleosomes can be approximated as disks 11 nm in diameter and 6 nm long. If all the DNA molecules in a diploid human cell are in the B-conformation, what is the sum of their lengths If this DNA is now arrayed on nucleosomes in the "beads-on-a-string" motif, what is its approximate total length
