Dna is tightly wrapped around
WebChromatin is the complex of DNA and proteins that are packed within the nucleus of mammalian cells. To form chromatin, DNA is tightly condensed by being wrapped around nuclear proteins called histones. This repeating DNA- histone complex, which consists of 146 base pairs of double-stranded DNA wrapped around eight histone proteins, is … WebDNA is able to wrap tightly around groups of 8 histones to form a nucleosome. This nucleosome can then be further compacted into chromatin and finally into a chromosome. Let’s look at the different answers to see which best describes the protein that DNA wraps around. Answer A, “hormones,” is incorrect. ...
