Which choice provides evidence that argues against the use of host cell RNA polymerases in replicating PSTVd RNA?

Question

Quizplus · Accepted Answer

Host cells typically contain DNA-dependent RNA polymerases, which transcribe DNA into RNA, not RNA into RNA or DNA. Since PSTVd (Potato Spindle Tuber Viroid) is an RNA molecule that requires replication of its RNA without a DNA intermediate, the presence of DNA-dependent RNA polymerases in host cells does not support their use in directly replicating PSTVd RNA.
