Which type of viruses must transport their genomes into the nucleus? A) Some viruses B) All viruses C) Only DNA viruses D) Only RNA viruses
Understand the Problem
The question is asking about the types of viruses that need to transport their genomes into the nucleus of a host cell. It presents multiple choice answers to identify the correct group of viruses.
Answer
Only DNA viruses
The final answer is C) Only DNA viruses
Answer for screen readers
The final answer is C) Only DNA viruses
More Information
Almost all DNA viruses require the transport of their genomes into the nucleus for replication. Only a few RNA viruses require nuclear entry, making the transport of genomes into the nucleus a characteristic primarily of DNA viruses.
Tips
A common mistake is to assume that all RNA viruses do not enter the nucleus. While most don’t, some RNA viruses, such as retroviruses, do enter the nucleus.
