Where does the newly produced viral DNA go?
They go and find a new host
What enzyme inserts viral DNA into the host's chromosomal DNA?
integrase
What makes copies of viral DNA?
ribosome
How do some viruses reproduce without possessing DNA?
39. When a virus attaches to a cell, it injects the cell with its DNA or RNA. This genetic coding material then implants itself into (or destroys) the DNA of the host cell. The viral genetic coding then induces mitosis, and the cell reproduces, and continues to make copies, until the immune response system of the organism reacts. Generally, viruses 'reproduce' by injecting the viral DNA into a host cell using the host cell's DNA synthesis enzymes to duplicate the viral DNA and the proteins that comprise the viral protein coat (capsid).
Difference between nucleoside reverse trancriptase inhibitor and non nucleoside reverse transcriptase inhibitor?
They have a different mode of action in inhibiting the transcription of the viral DNA. The NRTI is actually a nucleoside that incorporates into the viral DNA but it does not have a 3-hydroxyl group so it inhibits and halts the continued growth of the viral DNA chain. The NNRTI's bind to the reverse transcriptase and inhibit its movement.
Would you expect a viral DNA to code for ribosomal RNAs?
No. Viral DNA is going to code only for viral DNA. Viral RNA will code for viral RNA.

They go and find a new host
What enzyme inserts viral DNA into the host's chromosomal DNA?
integrase
What is viral DNA incorporated in bacterial DNA called?
The introduction of viral DNA into the host genetic structure is called lysogeny. And this is lysogenic cycle.
What makes copies of viral DNA?
ribosome
Why do viruses depend in host cells?
Viruses are composed of protein and DNA. The DNA encodes the protein as well as the DNA for the virus. Viruses depend on host cells because they are incapable of reproducing themselves. They enter the host cell and the viral DNA is inserted into the host DNA. The virus then "hijacks" the host cells replication machinery to make more viral protein and viral DNA.
why do bacteria have restriction enzymes?
to destroy viral DNA
What happens after genetically modified plasmids inserted into bacteria?
Plasmids are cloned and start producing protein .
What type of viral infection can lead to altered host cell genetics?
DNA viruses usually enter the nucleus and alter the DNA in order to produce new viral particles so I guess the answer is any DNA virus.
What is mode of action of adefovir?
adefovir mode of action through suppress the viral replication by inhibition of reverse transcription of viral dna which terminate chain of viral replication that adefovir depovixil transformed to active metabolite adefovir tri phosphate that incorporated into the viral Dna that terminate the chain of replication
Are nucleoside analogs that inhibit DNA synthesis effective against viral diseases?
yes, nucleoside analogues are artificial nucleosides. The block the completion of new viral DNA chains, therefore, preventing the production of new viral bodies. This way the viral enzyme, reverse transcriptase is more likely to incorporate the nucleoside analogue into the DNA than the host's DNA polymerase.
