__________ arranges the DNA into the chromosomes in a eukaryotic cell.
- A. Hormones
- B. Elastin
- C. Histone
- D. Nucleosome
Explanation
Histones are small positively charged proteins that the negatively charged DNA winds around, condensing roughly two metres of DNA into a nucleus a few micrometres across. A nucleosome is the resulting bead of DNA wrapped around eight histones, so it is the product of the packaging rather than the agent doing it, which makes it the deliberate near miss here. Elastin is a structural protein of connective tissue.
