Function of restriction enzymes?
They cut strands of DNA at specific sites.
If there is no restriction enzyme in eukaryotes how the proliferation of virus is restricted in eukaryotes?
They use a different mechanism: RNAi short of RNA interference, cleaves the virus genome (usually double stranded RNA) and destroys any strand that is complementary to the viral genome. -eukaryotic viruses are usually RNA viruses so they eukaryotes don't really restriction enzymes to protect against viruses.
What enzyme is needed to turn a RNA virus into a DNA virus?
The enzyme needed to convert RNA into DNA in a process called reverse transcription is called reverse transcriptase. This enzyme is unique to retroviruses, such as HIV, which use it to convert their RNA genome into DNA once they infect a host cell.
A key enzyme utilized by an RNA virus is what?
An RNA-dependent RNA polymerase is a key enzyme utilized by RNA viruses. It is responsible for replicating the viral RNA genome within host cells, enabling the virus to generate new copies of itself and continue infecting host cells.
Can your cold or virus cause your liver enzyme levels to rise?
Yes, viral infections like hepatitis can cause liver enzyme levels to rise. However, the common cold typically does not directly impact liver enzyme levels. If you are experiencing elevated liver enzymes, it is important to consult with a healthcare provider to determine the underlying cause.
Why restriction enzyme cannot cut its own DNA?
Restriction enzymes are produced by bacteria to help destroy foreign, invading DNA, such as the DNA of bacteriophage (a virus that infects bacterial cells). Every restriction enzyme comes with a methylase enzyme, or more specifically, a DNA methyltransferase. The methylase enzyme methylates (adds a methyl group) to the restriction endonuclease site on the cell's own DNA, which protects the sites from the restriction enzyme so that it does not degrade its own DNA.
How bacteria can protect themselves from attack by virus?
It produce some type of anzyme callet restriction enzyme that cut the foreing DNA of the virus that have been previoslly integrated into the host genome.
What is the neurominidase of a virus?
This is an enzyme that helps the virus to break out of the cell and so they can attack other cells and spread. Since this is an enzyme, a drug that is an enzyme inhibitor can be made to block it. The mumps and influenza viruses have this enzyme. Two such drugs that block this enzyme are oseltamivir (Tamiflu) and zanamivir (Relenza). These two are used for the influenza virus.
Function of restriction enzymes?
They cut strands of DNA at specific sites.
Is a virus a proton a enzyme a pathogen or a antibiotic?
All viruses are obligate pathogens.
What is the function of integrase?
integrase its is an enzyme that integrate virus gonome to the host genome.
Which enzyme are retroviruses equiped with that allows them to transcribe DNA from an RNA template?
Human Immunodeficiency Virus (HIV) is a retrovirus. A retrovirus is a RNA virus that replicates through a DNA intermediate. HIV synthesises DNA from RNA by the action of reverse transcriptase enzyme.
If there is no restriction enzyme in eukaryotes how the proliferation of virus is restricted in eukaryotes?

The enzyme needed to convert RNA into DNA in a process called reverse transcription is called reverse transcriptase. This enzyme is unique to retroviruses, such as HIV, which use it to convert their RNA genome into DNA once they infect a host cell.
Which enzyme is required for RNA virus to multiply in the host cell?
Reverse transcriptase. Runs off a DNA strand(s) from the virus RNA template.
What happens when RNA is extracted from a virus is injected into a host cell?
Without the viral enzyme reverse transcriptase probable nothing. RNA viruses are retroviruses because they nee reverse tanscriptase to make a DNA copy from the RNA that is inserted into the cell. Generally to form a provirus. Now if you injected DNA from a regular virus then it would be as if the virus did it itself.
Can virus affect the rom of computer?
No
