Final answer:
The DNA wraps around an octamer of histones to form the nucleosome. Each nucleosome contains eight histone molecules, two copies each of H2A, H2B, H3, and H4. 146 base pairs of DNA are associated with 1 histone octamer.
Step-by-step explanation:
The DNA wraps around an octamer of histones to form the nucleosome. Each nucleosome contains eight histone molecules, two copies each of H2A, H2B, H3, and H4. The DNA winding around the histone octamer is about 146 base pairs long. So, 146 base pairs of DNA are associated with 1 histone octamer.
