Which of the Following is True of Viruses

Question

Which of the following is true of viruses?
A)They manufacture their own ATP, proteins, and nucleic acids.
B)They use the host cell to copy themselves and make viral proteins.
C)They use the host cell to copy themselves and then viruses synthesize their own proteins.
D)They metabolize food and produce their own ATP.
E)They copy themselves but are unable to make proteins.

Accepted Answer

Viruses are obligate intracellular parasites which means they require a host cell to produce new virions. They cannot independently produce their own ATP, proteins, or nucleic acids. Instead, they utilize the host cell's machinery to replicate their genetic material and synthesize viral proteins. Consequently, option (B) is the correct answer.
