Answer:
Explanation:
The major chemical components of chromosomes are DNA, RNA, histone proteins and nonhistone proteins. Calcium is also present in addition to these constituents.
DNA:
DNA is the most important of chemical components of chromatin, since it plays the central role of controlling heredity.
Non-histones. The non-histone proteins display more but still limited diversity. In a variety of organisms, number of non-histones can vary from 12 to little more than 20. Heterogeneity of these proteins suggested that these proteins are not as conserved in evolution as histones. These non-histone proteins differ even between different tissues of the same organism suggesting that they regulate the activity of specific genes.
