Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Chromosomes are thread-like structures in which DNA is tightly packaged within the nucleus. DNA is coiled around proteins called histones, which provide the structural support. Chromosomes help ensure that DNA is replicated and distributed appropriately during cell division. Each chromosome has a centromere, which divides the chromosome into two sections – the p (short) arm and the q (long) arm. The centromere is located at the cell’s constriction point, which may or may not be the center of the chromosome.
Advantages of chromosomes ....
Having large number of chromosomes can be advantageous if the organism has a complete extra set of chromosomes. Having extra sets of chromosomes compared to other species that have the same but fewer sets is called being polyploid. Organisms are constantly under assault from their environment. Having extra sets of chromosomes makes them better able to cope with the pressures that threaten to wipe them out.
