The Function of Chromosomes. Chromosomes are the thread-like structure found in the nuclei of both animal and plant cells. They are made of protein and one molecule of deoxyribonucleic acid (DNA). ... During this cell division, DNA must remain intact and keep its even distribution through out the cells.

♦ What are Chromosomes?
Chromosomes are the thread-like structure which are found in the nuclei of both animal and plant cells.
They are made of protein and one molecule of deoxyribonucleic acid [ DNA ].
♦ Functions :
i. The most important function of chromosomes is to provide the genetic information for various cellular functions essential for growth, survival, development, reproduction, etc. of organisms.
ii. Chromosomes protect the genetic material (DNA) from being damaged during cell division. Chromosomes are coated with histones and other proteins which protect it from both chemical (e.g., enzymes) and physical forces.
iii. They ensure a precise distribution of DNA (genetic material) to the daughter nuclei during cell division.
iv. Centromeres of chromosomes perform an important function in chromosome movements during cell division which is due to the contraction of spindle fibres attached to the centromeric regions of chromosomes.
v. Gene action in eukaryotes is believed to be regulated through histone and non-histone proteins associated with chromosomes.
Hope it helps! :D
