How does a virus reproduce? Virus: Viruses are microscopic obligate parasites which thought to occur as a link between the living and the non-living because these organisms are inert outside their host but came to their living state inside the host body. These organisms contain DNA or RNA as...
How an RNA virus could insert DNA copies into a host's cell? How can it have DNA as an RNA virus? Explain. What is the role of RNA? How does protein synthesis differ between prokaryotes and eukaryotes? Is the difference between RNA and DNA that the RNA duplicates itself in the cytoplas...

An early host defense against infection by RNA or DNA viruses is the induction, within infected cells, of tumor necrosis factor-alpha (TNF-alpha) gene transcription. The protein product of the TNF-alpha gene alone, or together with different types of interferons, inhibits viral propagation in di...
Lactate dehydrogenase-elevating virus (LDV) is currently considered to be an unclassified togavirus. The 3′ terminus of the genome RNA of the C-strain of LDV was cloned and sequenced. A synthetic DNA oligomer complementary to the 3′ portion of this cloned sequence was then used to prime di...

(MCF7) which expresses the erbB2 or neu oncogene, MOPC315 cells as neu-negative controls, and antisense DNA oligonucleotides complementary to the 5′ region of the mRNAs and the sense sequence, we have shown that there is a preferential, specific retention of the IgA andneu antisense sequence...
cases, there is a stage in which the virus lies dormant. This means that the viral RNA stays integrated within the host cell’s DNA but does not get translated into proteins. This stage is called the latency stage, and it can last anywhere from a few days to years, or even a life...
Viruses are generally made up of either DNA or RNA and a protein capsid. Unlike microorganisms which can replicate on their own, viruses can only replicate inside a host cell. The first discovered virus was the Tobacco Mosaic virus in 1935 by American scientist Wendell Stanley....
What are the basic building blocks of DNA and RNA? What is the secondary structure of transfer RNA? What is an example of transfer RNA? Do viroids have RNA? Can RNA be double-stranded? What RNA virus replicates in the nucleus? Does an RNA virus have DNA?
