What two substances are in a virus?

Answer 1

There are two types of macromolecules in a virus: a protein coat and its own set of viral RNA or sometimes DNA, both contained in its head. It can also have a tail of fibers or phospholipid bilayer to easily attach to the membrane of the host cell.

Answer 2

Virus is a minute nucleoprotien particle

consist of a central core of nucleic acid

and protienaceous coat which sround the nucleic acid.

In viruses either DNA or RNA is present.In it RNA or DNA are linear or

circular in shape .Protien coat or capsid is made up of many structural

identical units called capsomeres.Composition ,number and structure of

viruses are different from each other .The capsids with its nucleic acid

called Nucleicapsid of the virus.In some mammalian viruses limiting membrane

is present outside the membrane. limiting membrane is made up of

peplomeres.

Answer 3

DNA . it injects it into bacteria in the body to reproduce that DNA

Answer 4

A virus contains genetic material (either DNA or RNA) and protein coat (capsid) surrounding the genetic material.
