Conversely, several polyomaviruses downregulate the expression of the viral T antigens, key early transcription factors, at late stages in the viral replication cycle [8],[9],[10].

Umbach and B. In addition, deep sequencing of small RNAs isolated from cells infected with cowpox virus or influenza A virus has also failed to identify any virally encoded miRNAs (J. Multiple Choice Questions On Viruses In contrast, while KSHV does not induce miR-155 expression upon infection of B cells, it does encode a viral miRNA that functions as an ortholog of miR-155 [17],[18]. Viruses Quiz Questions Almost all cellular miRNAs are initially transcribed by RNA polymerase II (Pol II) as part of a long, capped, polyadenylated primary miRNA (pri-miRNA) precursor.

Possible Answers: RNA Ribosomes DNA Proteins Correct answer: Ribosomes Explanation: Viruses use the hosts ribosomes to translate their genes, and do not possess their own organelles for replication. More about the author Do these Subject Areas make sense for this article? Many viruses globally repress Pol II transcription in infected cells, and this would also repress miRNA biogenesis.

Some scientists argue that there must be a virus or bacterium that cause infectious diseases, and claim that there is likely a heretofore undiscovered microbe causing neurodegeneration that most scientists claim

Once infection is established, Neisseria preferentially infects columnar epithelial cells in the female reproductive tract, and leads to a loss of cilia on these cells. Of note, RISC is believed to direct bound mRNAs into cytoplasmic processing bodies (P bodies), where they may be translationally repressed and/or degraded, yet emerging evidence suggests that P bodies can HIV is an RNA virus.
