Detailed explanation-1: -Chromosomes are structures found in the center (nucleus) of cells that carry long pieces of DNA. DNA is the material that holds genes. It is the building block of the human body. Chromosomes also contain proteins that help DNA exist in the proper form.
Detailed explanation-2: -Chromosomes come in pairs. Normally, each cell in the human body has 23 pairs of chromosomes (46 total chromosomes). Half come from the mother; the other half come from the father.
Detailed explanation-3: -The first 22 pairs of chromosomes are called autosomes. The 23rd pair of chromosomes are known as the sex chromosomes, because they decide if you will be born male or female.
Detailed explanation-4: -Chromosomes are very important because they contain the vast majority of genetic information of organisms. The organism’s DNA is contained within the chromosome as a gene that helps to inherit the characteristics of parents to their offspring.
