Detailed explanation-1: -Chromatin is located in the nucleus of our cells. Its primary function is packaging very long DNA molecules into a more compact, denser shape, which prevents the strands from becoming tangled. During cell division, chromatin condenses to form chromosomes.

Detailed explanation-2: -In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes.

Detailed explanation-3: -The thread-like structure located inside the nucleus of cells of plants and animals is called a chromosome.

Detailed explanation-4: -Chromatin Chromatin refers to a mixture of DNA and proteins that form the chromosomes found in the cells of humans and other higher organisms. Many of the proteins-namely, histones-package the massive amount of DNA in a genome into a highly compact form that can fit in the cell nucleus.

Detailed explanation-5: -A DNA molecule consists of two long polynucleotide chains composed of four types of nucleotide subunits. Each of these chains is known as a DNA chain, or a DNA strand.
