What happens when genes are altered by a deadly virus?
they change their DNA and turn into a virus and can now be dangerous they change their DNA and turn into a virus and can now be dangerous they change their DNA and turn into a virus and can now be dangerous they change their DNA and turn into a virus and can now be dangerous
A key enzyme utilized by an RNA virus is what?
Some retroviruses may utilize a special enzyme known as reverse transcriptase, which a RNA virus can use to make DNA using the RNA as a template.
What is the function of restriction enzymes in the process of DNA recombination?
First, a specific enzyme is needed to cut the DNA from the donor genes at a specific site. This enzyme is called a restriction enzyme.The enzyme is used to cut out a piece of DNA that contains one or more desired genes from the donor's DNA. Next, a vector is needed to receive the donor DNA. Most frequently, a naturally occurring circular piece of bacterial DNA, called a plasmid, is used for this purpose. Finally, an enzyme is used to "stitch" the donor DNA into the plasmid vector. This enzyme is called ligase, and it creates permanent bonds between the donor DNA and the plasmid DNA. The result is that the donor DNA is incorporated into the bacterial plasmid, forming the recombinant DNA (rDNA)
What is an example of a biological enzyme?
DNA helicase. This is the enzyme that "unzips" DNA.
What is the type of virus that codes backwards from RNA to DNA?
That is called a retrovirus. The enzyme used to code in that direction is called reverse transcriptase.

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
Which enzyme would probably not be needed for DNA replication?
DNA helicase
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.
How does a retrovirus differ from other viruses?
A retrovirus transcribes RNA into DNA, whereas a regular virus transcribes DNA into RNA. (:

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 is a reterovirus?
A retrovirus is an RNA virus that is replicated in a host cell via the enzyme reverse transcriptase to produce DNA from its RNA genome. The DNA is then incorporated into the host's genome by an integrase enzyme. The virus thereafter replicates as part of the host cell's DNA. Retroviruses are enveloped viruses that belong to the viral family Retrovirida.
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 enzyme connects the new bases to the old bases in the DNA template?
The central enzyme involved is DNA polymerase, which catalyzes the joining of deoxyribonucleoside 5′-triphosphates (dNTPs) to form the growing DNA chain.
The aids virus a retrovirus uses what to read RNA and synthesize the corresponding DNA?
An enzyme called Reverse transcriptase.
