Detailed explanation-1: -Nuclei contain the genetic material called DNA that is responsible for controlling and directing all cell activities. This is a very important organelle given its vital function.
Detailed explanation-2: -Today, we know that DNA is the genetic material: the molecule that bears genes, is passed from parents to children, and provides instructions for the growth and functioning of living organisms.
Detailed explanation-3: -Genetic information in bacteria and many viruses is encoded in DNA, but some viruses use RNA. Replication of the genome is essential for inheritance of genetically determined traits.
Detailed explanation-4: -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-5: -Genetic material is the hereditary substance in the cell. It carries all information specific to an organism. It is known as DNA (deoxyribonucleic acid) or RNA (ribonucleic acid).
