Answer 2

hey mate here is your answer

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells

Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA).

Chromatin material is a mass of genetic material consisting of DNA and histoneprotei so. Before the cell divides,the chromatin material packages itself more tightly for facilitation of segregation of the chromosomes
