Question

DNA packing is done by which of the following?

• A. Histone
• B. Glycoprotein
• C. Nucleic acid
• D. Adenine

Answer 1

The Correct Option is A

In the process of DNA packing within the cell nucleus, DNA is wrapped around proteins known as histones. Histones are crucial components as they facilitate the compaction of DNA into a nucleosome, which forms the fundamental unit of chromatin structure. Each nucleosome consists of a segment of DNA wound in sequence around eight histone protein cores. This compact structure allows long DNA molecules to be efficiently organized within the limited space of the cell nucleus. Therefore, among the options provided, the correct answer is:

Histone
