Detailed explanation-1: -There are two main types of genetic material: DNA and RNA. In eukaryotic cells, which have a nucleus and membrane bound organelles, the DNA is stored in the nucleus wrapped round proteins called histones. In prokaryotic cells, the DNA exists in the cytoplasm.

Detailed explanation-2: -The nucleus contains genetic (hereditary) material. Genetic material, written in deoxyribonucleic acid (DNA), provides instructions for the cell. All cells contain the same DNA (the same set of instructions), but cell types are different because of different gene expression.

Detailed explanation-3: -Leuko virus contains both DNA and RNA.

Detailed explanation-4: -The genetic material of bacteria and plasmids is DNA. Bacterial viruses (bacteriophages or phages) have DNA or RNA as genetic material. The two essential functions of genetic material are replication and expression.

Detailed explanation-5: -Though both the nucleic acids can act as genetic material, DNA is much more preferred. DNA is stable both chemically and structurally which make it well-built genetic material. RNA in humans does not act as a genetic material but play various other roles such as an adapter, enzyme, helps in protein synthesis, etc.
