... ." HIV begins its assault by injecting its single-stranded RNA into a host cell. Three subsequent ... DNA is replicated into double-stranded DNA, and the original viral RNA is degraded. Another enzyme ...

... . Special proteins recognize the resulting double-stranded RNA, and chemically slice it to release regulatory ... up with copies from the related pseudogenes, resulting in double-stranded RNAs that -- far from being junk -- are able to activate ...

... with characteristic, newly induced double membrane vesicles. The cellular pathways hijacked by these plus-strand RNA viruses to create these "factories" have thus ...

... of TLR3 who undergo a new treatment called RNA interference (RNAi) could be at risk. A class of double-stranded RNA (like the genetic information carried ...

... syndrome (SARS)-coronavirus killed over 750 people. SARS (corona)virus, a positive-stranded RNA virus, replicates in the cytoplasm of host cells, attaching its replication complex to intracellular membranes ...

... , when an infected cell is exposed to a virus, double-stranded RNA molecules are formed triggering a potent ... interact to form tiny tubules. The double-stranded RNA is hidden or sequestered in these structures. The cell ...

... virus strain called H5N1 forms tiny tubules in which it "hides" the pieces of double-stranded RNA formed during viral infection, which otherwise would prompt an antiviral immune response ...

... its assault by injecting its core that contains a single-stranded RNA into a host cell. Once inside, the viral RNA is converted into double-stranded DNA—a process known as reverse transcription—and the original ...
