what is chromosom?? and why chromosome called chromosome
Answers
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.
Answer:
Chromosomes are rod shaped structures found in the nucleus of the cell. Chromosomes contain information for inheritance of features from parents to next generation in the form of DNA molecule.
The two gametes fuse during fertilisation and the offspring become diploid (2n) which is same as parents chromosomes number.
