Detailed explanation-1: -Between cell divisions, the DNA in chromosomes is more loosely coiled and forms long thin strands called chromatin. DNA is in this uncoiled form during the majority of the cell cycle, making the DNA available to the proteins involved in DNA replication and transcription.
Detailed explanation-2: -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-3: -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-4: -Gene is known as the length of DNA as it codes for protein.
