Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A virus is a strand of DNA or RNA surrounded by-this ____
A
a protein coat
B
a capsule
C
a cell membrane
D
a cell wall
Explanation: 

Detailed explanation-1: -Viruses are small obligate intracellular parasites, which by definition contain either a RNA or DNA genome surrounded by a protective, virus-coded protein coat.

Detailed explanation-2: -Viruses are made up of nucleic acids (DNA or RNA) surrounded by a protein coat. They are smaller than the smallest bacterium. Viruses consist of nucleic acid (genetic material) surrounded by a capsid (protein coat).

Detailed explanation-3: -A virus is made up of a DNA or RNA genome inside a protein shell called a capsid.

Detailed explanation-4: -Statement is false. Not always it will be double stranded.

Detailed explanation-5: -Viruses have a protein coat called capsid, that encloses their genetic material.
