Unable to do much of anything on their own, they go into hosts cells to reproduce, often wreaking havoc and causing disease. Their ability to move genetic information from one cell to another makes them useful for cloning DNA and could provide a way to deliver gene therapy.

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A	DNA sample
B	Virus
C	None of these
D	Protozoa

Explanation:

Detailed explanation-1: -Specifically, they are pieces of genetic material (RNA or DNA) contained in a special coating of proteins called capsids. Viruses cannot replicate unless absorbed by cells in our body. Once a virus is outside the body, its capsid starts to degrade, and the more degraded its capsid is, the less likely it is to survive.

Detailed explanation-2: -They do not possess ribosomes and cannot independently form proteins from molecules of messenger RNA. Because of these limitations, viruses can replicate only within a living host cell.

Detailed explanation-3: -Effects on Cell Biochemistry: Many viruses inhibit the synthesis of host cell macromolecules, including DNA, RNA, and protein. Viruses may also change cellular transcriptional activity, and protein-protein interactions, promoting efficient production of progeny virus.
