Detailed explanation-1: -DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA.
Detailed explanation-2: -The hereditary material present in all cells is DNA. It is passed from one generation to another through genes. Genetic information links previous generations to an individual. Individual characteristics such as hair and skin color are carried on genes together with other invisible or recessive characters.
Detailed explanation-3: -In 1952, Alfred Hershey and Martha Chase took an effort to find the genetic material in organisms. Their experiments led to an unequivocal proof to DNA as genetic material. Bacteriophages (viruses that affect bacteria) were the key element for Hershey and Chase experiment.
Detailed explanation-4: -DNA is important in terms of heredity. It packs in all the genetic information and passes it on to the next generation. The basis for this lies in the fact that DNA makes genes and genes make chromosomes.
