TLR-3 recognizes double-stranded RNA.The presence of double stranded RNA in a cell usually indicates the cell is infected by which of these?

Question

Quizplus · Accepted Answer

Double-stranded RNA is a common feature of RNA viruses, which replicate their genetic material in double stranded form. Gram negative and Gram positive bacteria, protozoans, and yeast typically have single-stranded RNA or DNA genomes, and are less likely to produce double-stranded RNA. Therefore, the presence of double-stranded RNA is a strong indication of an RNA virus infection.
