which part of the cell are not present in a virus?

Answer 1

The first answer was the closest.

Viruses have nucleic acids, proteins and sometimes membranes. Viruses do not have organelles, nuclei or cytoplasm.

PS Most viruses do not have lytic or lysogenic life cycle phases. Bacteria do not produce interferon. Most viruses do enter the cells as intact virions, not as nucleic acids. If you don't know what you're talking about you shouldn't try to elaborate.

Answer 2

virus is the connecting link between living and non living.

it basically lacks everything a normal cell has except a cell membrane and genetic material which may be DNA or RNA as in retroviruses.

viruses a inactive outside a host and do not have their own meetabolic machinery . they are like machines the only difference being that they can reproduce.

inside a host viruses have 2 types of life cycle i.e lytic and lysogenic and they are very harmful to organisms. only interferons secreted by bacteriophage infected bacteria can do anything to stop them by stopping their protein synthesis mechanism.

Answer 3

A virus is not a cell. Most of them cannot replicate outside their hosts. They basically carry a very abbreviated genetic information (DNA or RNA) surrounded by a protein capside (no cytoplasmic structures, no membranes, no cell wall). The only part that enters the cell is, normally, the genetic material.

Answer 4

Virus is like a soft ware while the rest of the cells are like harware. It is nor right to compare these two structures.
