Explanation:
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: -Between cell divisions, the DNA in chromosomes is more loosely coiled and forms long thin strands called chromatin.
Detailed explanation-3: -DNA, Histones, and Chromatin The answer to this question lies in the fact that certain proteins compact chromosomal DNA into the microscopic space of the eukaryotic nucleus. These proteins are called histones, and the resulting DNA-protein complex is called chromatin.
