Question

A network
chromatin of thread like structures in the
fibres-​

Answer 1

Answer:

DNA packaging into chromatin and chromosomeDNA wraps around proteins called histones to form units known as nucleosomes. These units condense into a chromatin fibre, which condenses further to form a chromosome.

Answer 2

Answer:

Chromatin is a complex of macromolecules composed of DNA, RNA, and protein, which is found inside the nucleus of eukaryotic cells. Chromatin exists in two forms: heterochromatin (condensed) and euchromatin (extended). The primary protein components of chromatin are histones that help to organize DNA into “bead-like” structures called nucleosomes by providing a base on which the DNA can be wrapped around. A nucleosome consists of 147 base pairs of DNA that is wrapped around a set of 8 histones called an octomer. The nucleosome can be further folded to produce the chromatin fiber. Chromatin fibers are coiled and condensed to form chromosomes. Chromatin makes it possible for a number of cell processes to occur including DNA replication, transcription, DNA repair, genetic recombination, and cell division.The Structure and Function of Chromatin
