FUNCTIONS OF CHROMOSOMES:

1,Essential unit for cellular division.
2, Chromosomes replicated,divided and passed to daughter cells for their survival.
3, Chromosomes protect DNA from damage.
4,It plays a vital role for genetic diversity.
5,Dynamic of chromosome structural changes regulate the gene expression.
Hope this will helpful for you ?.

Functions of Chromosomes
Chromosomes play a vital role in availing the genetic information of living organisms with the help of its ultrastructure diagram. 
* Chromosomes assist in the growth of reproduction, regeneration and repair process, which is an essential survival element.
*The ultrastructure of the chromosome prevents deoxyribonucleic acid or DNA coils from being damaged and intertwined.
*Transferring genetic material from one peer group to another is the primary function of chromosome cells.
*DNA coils around a protein called histones that help in balancing the gene’s impression in living organisms.
*The chromatids that connect with the centromere support the motion of chromosome cells at the time of cell division.
*Chromosomes have thousands of genes that directly provide codes for various proteins adjacent to living species.
*DNA present in living organisms assists in controlling innate transfer.
As chromosomes hold the deoxyribonucleic acid tightly and deliver proteins in eukaryotic cells, they are called “packaging material”.
*Chromosomes play an essential role in replication, cell division, and the creation of daughter cells as the ultrastructure chromosome helps separate copies by creating new complete sets.

IMPORTANT FUNCTION OF THE CHROMOSOME:
1. The most important function of chromosomes is to carry the basic genetic material – DNA.
=> DNA provides genetic information for various cellular functions. These functions are essential for growth, survival, and reproduction of the organisms.
2. Histones and other proteins cover the Chromosomes.
=> These proteins protect it from chemical (e.g., enzymes) and physical forces. Thus, chromosomes also perform the function of protecting the genetic material (DNA) from damage during the process of cell division.
3. During cell division, spindle fibers attached to the centromeres contract and perform an important function.
=>The contraction of centromeres of chromosomes ensures precise distribution of DNA to the daughter nuclei.
4. Chromosomes contain histone and non-histone proteins.
=> These proteins regulate gene action, Cellular molecules that regulate genes work by activating or deactivating these proteins. This activation and deactivation expand or contract the chromosome.
