WebChromosomes. Bacterial chromosomes are located in a nucleoid, a distinct cytoplasmic structure, in which double-stranded DNA is coated with histone-like proteins. Most bacteria appear to have a single large circular chromosome, but this is not universal.

WebIn bacteria, the DNA is freely accessible to RNA polymerase and regulatory proteins. However, in eukaryotes, the DNA is coiled around the histones, forming nucleosomes, as discussed in Chapter 4, Genes, Genomes, and DNA. The nucleosomes are wound into a helix and held close together largely by interactions between the histone proteins. WebThe answer to this question lies in DNA packaging. Whereas eukaryotes wrap their DNA around proteins called histones to help package the DNA into smaller spaces, most prokaryotes do not have ... So how does nature resolve this problem?
