DNA and RNA are the two types of genetic material. Genetic material
refers to the materials that are found in the nuclei and cytoplasm. They
play a fundamental role in determining the nature and structure of a
cell. They carry the hereditary information from generation to
generation. They carry the information that tells a cell what to do,
kind of like blueprints. The strands are made of a special sugar,
nitrogen bases, and phosphate groups. So to pass all the characters from
generation to generation copying of DNA is essential.
