Question

In a ecoli 4.6×{10}^{6} (4.6×10 power 6) bps are present than how many nucleosomes are present??

My doubt is prokaryotic cell lacks histone proteins than how could it form nucleosomes?

Answer 1

Ans: is zero as Ecoli is a prokaryote so its doesnt have histone proteins/ nucleosome...

Whereas eukaryotes wrap their DNA around proteins called histones to help package the DNA into smaller spaces, most prokaryotes do not have histones (with the exception of those species in the domain Archaea). Thus, one way prokaryotes compress their DNA into smaller spaces is through supercoiling...
