Detailed explanation-1: -Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells. Nuclear DNA does not appear in free linear strands; it is highly condensed and wrapped around nuclear proteins in order to fit inside the nucleus. Chromatin exists in two forms.

Detailed explanation-2: -The nucleus is the most conspicuous organelle found in a eukaryotic cell. It houses the cell’s chromosomes and is the place where almost all DNA replication and RNA synthesis occurs. The nucleus is spheroid in shape and separated from the cytoplasm by a membrane called the nuclear envelope.

Detailed explanation-3: -The nucleus is enclosed by the nuclear membranes. It is covered by a structure called the nuclear envelope. The cell’s chromosomes are also cramped within the nucleus. DNA is present within the chromosomes, it provides the genetic information for the creation of different cell components including reproductive cells.

Detailed explanation-4: -Each eukaryotic chromosome is composed of DNA coiled and condensed around nuclear proteins called histones. Humans inherit one set of chromosomes from their mother and a second set from their father.
