Detailed explanation-1: -In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Detailed explanation-2: -Chromatin is visible as entangled mass of thread like structures.
Detailed explanation-3: -Chromatin refers to a mixture of DNA and proteins that form the chromosomes found in the cells of humans and other higher organisms.
Detailed explanation-4: -The DNA + histone = chromatin definition: The DNA double helix in the cell nucleus is packaged by special proteins termed histones. The formed protein/DNA complex is called chromatin. The basic structural unit of chromatin is the nucleosome.
Detailed explanation-5: -Chromatin is the complex of genomic DNA with proteins called histones, where each histone-bound DNA molecule is referred to as a chromosome. However, chromatin not only compacts the genome into the nucleus, but is also the mechanism controlling how the genome is read out from cell to cell.
