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.
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.
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.
What enzyme manufactures DNA that is complementary to a virus's RNA?
reverse transcriptase
What is the relationship that exist between a virus and a human when the virus infects the human?
pathogen/host
What is the most common threat to the human body from an invading virus?
Swine Flu or scientifically pronounced (H1N1)
What type of pathogen is HIV?
HIV, the human immunodeficiency virus, is itself a pathogen.HIV is a virus.HIV itself is a pathogen Human Immunodeficiency virus cause HIV/AIDS disease it belongs to retro virus which has ability to convert mRNA to DNA the reverse transcription and possess reverse transcriptase enzyme
Drugs which fight HIV by deactivating an enzyme which the virus needs to be able to in fect human blood cells?
Protease inhibitors.
An invading foreign material such as that on a virus is an?
antigen
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.

What HIV enzyme is essential for its successful replication in a host cell?
Reverse transcriptase is the enzyme that permits the HIV virus to enter the cell. There are other human diseases that are also caused by other viruses using a reverse transcriptase.
What enzyme is needed to turn a RNA virus into a DNA virus?
Reverse transcriptase or RT.
How does enzyme restriction limit the affect of a virus?
Effect
The virus that causes AIDS is damaging to the body because it?
targets cells that fight invading microbes
Can your cold or virus cause your liver enzyme levels to rise?
Your cold or virus certainly can cause your liver enzyme levels to rise. There are a number of other factors that could cause this as well.
