Viruses do not synthesize enzymes rather they have enzymes, some enzymes are carried within the capsid, some are carried on the viral envelope and some are only produced in the infected cell.

Which of the following is true for a virus : -a)That a virus does not ...
Explanation:
A virus is a microscopic infectious agent that replicates only inside the living cells of an organism. It consists of genetic material, either DNA or RNA, surrounded by a protein coat called a capsid. Some viruses also have an outer envelope made of lipoproteins. Let's discuss the given options in detail to understand why option 'C' is the correct answer.
a) That a virus does not possess D.S. DNA:
- This statement is not true. Viruses can have either single-stranded (S.S.) DNA or double-stranded (D.S.) DNA as their genetic material.
- Examples of viruses with D.S. DNA include Herpesviruses, Adenoviruses, and Poxviruses.
b) That a virus does not possess a membrane of lipoproteins:
- This statement is also not true. Some viruses have an outer envelope made of lipoproteins.
- The envelope is derived from the host cell's membrane during the process of viral replication and release.
- Examples of enveloped viruses include Influenza viruses, HIV, and Hepatitis C virus.
c) That a virus does not synthesize enzymes:
- This statement is true. Viruses do not possess the machinery necessary for synthesizing enzymes.
- Unlike living cells, viruses cannot carry out metabolic processes on their own.
- They rely on host cell machinery to replicate and produce viral proteins.
- Once inside a host cell, the viral genetic material takes control of the cell's machinery to replicate itself and produce viral enzymes and proteins.
d) That a virus does not possess any enzyme:
- This statement is not true. Some viruses do possess enzymes that are required for their replication and survival.
- For example, the reverse transcriptase enzyme is found in retroviruses like HIV, which converts the viral RNA into DNA.
- Other viruses may have enzymes involved in viral entry, replication, or release.
Conclusion:
Based on the given options, the correct answer is option 'C' - That a virus does not synthesize enzymes. Viruses lack the machinery for enzyme synthesis and rely on host cells for replication and protein synthesis.
