Question

Name the negatively charged and positively charged components of a nucleosome.

Answer 1

In nucleosome, the negatively charged component is a histone octamer and the positively charged component is DNA.

• Histones carry a positive charge because they are made up of amino acids.

• DNA carries a negative charge because they were linked with phosphodiester bonds.

• Chromatin consists of a basic subunit that is called a nucleosome.

• Nucleosome is comprised of structural proteins those are histone protein and DNA particles.

Answer 2

DNA & histone octamer

Explanation:

• The contrarily charged part is.DNA decidedly charged segment is histone octamer
• This is because A nucleosome is composed of histone protein and DNA. DNA carries the negative charge due to the phosphodiester linkage and histone are basic in nature and carry a positive charge because histones are made up of basic amino acids. DNA wrapped around the histone octamer (H2A-H2B, H3, H4 two copies of each) through the H- bonding. In this way, the adversely charged nucleosome is DNA and decidedly charged parts of nucleosome are histone octamer.
