NEET BIOLOGY

Detailed explanation-1: -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-2: -Although viruses are not classified as living things, they share two important traits with living things. They have genetic material, and they can evolve.

Detailed explanation-3: -Viruses contain either RNA or DNA as their genetic material. DNA in most organisms is a double-stranded structure, based on Watson and Crick pairing; however, in viruses, DNA and RNA can be either single-stranded or double-stranded.

Detailed explanation-4: -Cells have a double stranded DNA molecule and many strands of single stranded RNA as the copies. Viruses, however, can have double stranded DNA, single stranded DNA, double stranded RNA, or single stranded RNA. They convert RNA to DNA and then back to RNA to make proteins, which does not happen inside cells.

Detailed explanation-5: -The genetic material of viruses can be composed of DNA or RNA. All living cells, whether human, animal, plant, or bacterial, have double-stranded DNA (dsDNA) as their genetic material. Viruses, on the other hand, have genomes, or genetic material, that can be composed of DNA or RNA (but not both).
