Detailed explanation-1: -In eukaryotes, the cell’s genetic material, or DNA, is contained within an organelle called the nucleus, where it is organized in long molecules called chromosomes.
Detailed explanation-2: -The nucleus is particularly important among eukaryotic organelles because it is the location of a cell’s DNA.
Detailed explanation-3: -Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
Detailed explanation-4: -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.
