Expert Solution & Answer

Answer to Problem 1SQ

Correct answer:

Viruses can have a genome of either RNA or DNA. Hence, the correct answer is option c.

Explanation of Solution

Reason for correct answer:

Option c. is given as “Viruses.”

A virus is a noncellular infectious particle that replicates only inside a living cell. Their genome consists of RNA or DNA that may be single-stranded or double-stranded.

Reason for incorrect answer:

Option a. is given as, “Bacteria.”

Bacteria are single-celled and have a porous cell wall around their plasma membrane. A single circular double-stranded DNA is present in the cytoplasm. This indicates that bacteria contains DNA only. Hence, option a. is incorrect.

Option b. is given as, “Viroids”.

Viroids are plant pathogens and have single stranded RNA. Hence, option b. is incorrect.

Option d. is given as, “Archaea.”

Archaea are the prokaryotic organisms that are similar to bacteria in many respects. They have a single circular chromosome like bacteria. This indicates that archaea contains only DNA in their genome. Hence, option d. is incorrect.

Hence, the options a., b., and d. are incorrect.

Conclusion

The genome of virus consists of either RNA or DNA. Thus, the correct option is c.
