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: -DNA is normally found as a loosely contained structure called chromatin within the nucleus, where it is wound up and associated with a variety of histone proteins. When a cell is about to divide, the chromatin coils tightly and condenses to form chromosomes.
Detailed explanation-3: -Most DNA is found inside the nucleus of a cell, where it forms the chromosomes. Chromosomes have proteins called histones that bind to DNA.
Detailed explanation-4: -It’s in the middle of the cell, and the nucleus contains all of the cell’s chromosomes, which encode the genetic material.
Detailed explanation-5: -As described above, DNA can be found in three organelles: the nucleus, mitochondrion, and chloroplast. Only eukaryotes have a nucleus, which is a large structure that’s surrounded by a membrane.
