What is chromatin material and how does it change just before the cell divides?

Chromatin material is a genetic material body which consists of DNA and histone proteins, in other words:

The DNA + histone = chromatin

The basic structural unit of chromatin is the nucleosome.

The diagram is given below:

• As the cell initiates divisions by either meiosis or mitosis.

• During the interfaces, DNA is combined with the proteins and organized into a structure called chromatin.

• This chromatin is a thread like structure which condenses to form chromosomes just before the cell division occurs.
