AleksandrR [38]

Answer:

Chromosomes are systemized structures of proteins and DNA. It have a string like shape, mainly located within the nucleus of both plant and animal cells. DNA is concentrated in the chromosomes.

It ensures accurate distribution of the DNA during the breaking down of genetic material. In mitosis, the chromosomes are duplicated and dispersed to daughter cells so that each cell attains a diploid set of chromosomes totally of the same nature to that of its parent cell. In meiosis, the resultant cells would attain a chromosome from each chromosome pair this will lead to half the number of chromosomes. This process is important for the offspring being produced to have the same characteristics of the parents which would results from the fusion of the sperm and egg of the parents.
