Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Where are instructions for making new copies of a virus found in the virus? Select all that apply
A
DNA
B
RNA
C
protein capsid
D
None of the above
Explanation: 

Detailed explanation-1: -The viral genome (genetic material) has the instructions, aka genes, to take over the host cell and to build new copies of itself.

Detailed explanation-2: -Viruses cannot replicate on their own, but rather depend on their host cell’s protein synthesis pathways to reproduce. This typically occurs by the virus inserting its genetic material in host cells, co-opting the proteins to create viral replicates, until the cell bursts from the high volume of new viral particles.

Detailed explanation-3: -Unlike DNA, RNA can encode information and function in its structure as well as its sequence. This feature is exploited by all RNA viruses in one way or another. Coronaviruses, for example, use RNA structures to regulate their own genome replication, as well as to interact with host ribosomes.

Detailed explanation-4: -They do not contain the cellular machinery and the plasma membrane. However, they do contain genetic material in form of either DNA or RNA. The viruses that contain RNA as their genetic material are called retroviruses.
