Function of chromosome plssssssssl!!!!!

Answer 1

heyaa....




Functions of Chromosomes:

The role of chromosomes in heredity was suggested independently by Sutton and Bover in 1902. This and various other functions of chromosomes may be summarised as under.

✔1. It is universally accepted that DNA is the genetic material, and that in eukaryotes almost all the DNA is present in chromosomes. Thus, 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.

✔2. Another very important function of chromosomes is to 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.

✔3. The properties of chromosomes ensure a precise distribution of DNA (genetic material) to the daughter nuclei during cell division. 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.

✔4. Gene action in eukaryotes is believed to be regulated through histone and non-histone proteins associated with chromosomes.

Answer 2

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).
Chromosomes are important to this process to ensure the DNA is accurately replicated.
They transfer the heridity from parents to offspring!
