NEET BIOLOGY

Detailed explanation-1: -Viruses contain genetic material that is enclosed in a protein coat. The genetic material can be either RNA or DNA. No virus contains both RNA and DNA.

Detailed explanation-2: -The genetic information, which contains the information for the structure and function of the organism, is found encoded in DNA in the form of genes. A gene is a short segment of DNA that contains information to encode an RNA molecule or a protein strand.

Detailed explanation-3: -All viruses have genetic material (a genome) made of nucleic acid. You, like all other cell-based life, use DNA as your genetic material. Viruses, on the other hand, may use either RNA or DNA, both of which are types of nucleic acid.

Detailed explanation-4: -Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). Mitochondria are structures within cells that convert the energy from food into a form that cells can use.

Detailed explanation-5: -A retrovirus is a virus that uses RNA as its genomic material.
