Detailed explanation-1: -Genes are short pieces of DNA that carry specific genetic information.
Detailed explanation-2: -In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases. An international research effort called the Human Genome Project, which worked to determine the sequence of the human genome and identify the genes that it contains, estimated that humans have between 20, 000 and 25, 000 genes.
Detailed explanation-3: -Your chromosomes contain the blueprint for your body – your genes. Almost every cell in the human body contains a copy of this blueprint, mostly stored inside a special sac within the cell called the nucleus. Chromosomes are long strands of a chemical substance called deoxyribonucleic acid (DNA).
