Question

What is the main function of chromatin in a plant cell?

Answer 1

Chromatin:

Chromatin is a highly coiled structure formed by Eukaryotic DNA (negatively charged) and proteins (positively charged). Major proteins found in it are histone proteins. There are five major types of histone proteins – H1, H2A, H2B, H3, and H4.

As DNA is 2m long, so it is very difficult for the DNA to get accomodated in a small cell. So a coiled structure known as chromatin is formed.

And whenever the cell is about to divide, the chromatin material gets organised into structures known as chromosomes.

Main function of Chromatin:

The main function of chromatin is to compress and package long DNA molecules into compact, dense structures i.e. DNA is condesed into smaller volume.
