What else can I help you with?
What enzyme do you need to get a copy of DNA from mRNA?
The enzyme needed to make a DNA copy of RNA (including mRNA) is called reverse transcriptase. This enzyme is capable of synthesizing a complementary DNA strand from an RNA template, which is the first step in generating a cDNA (complementary DNA) library.
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
How does enzyme restriction limit the affect of a virus?
Enzyme restriction acts as a defense mechanism by cutting viral DNA at specific recognition sites, preventing the virus from replicating effectively in the host cell. This limits the virus's ability to spread and cause infection.
What enzyme is needed in order for transcription to take place?
RNA polymerase is the enzyme needed for transcription to take place. It catalyzes the synthesis of an RNA molecule from a DNA template.
What enzyme is needed to open the DNA molecule to make the RNA strand?
The enzyme needed to open the DNA molecule for RNA synthesis is RNA polymerase. It binds to a specific region of the DNA called the promoter and unwinds the double helix, allowing access to the template strand. This process initiates the transcription of DNA into RNA.
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.
Which enzyme would probably not be needed for DNA replication?
DNA helicase
How does a retrovirus differ from other viruses?
A retrovirus transcribes RNA into DNA, whereas a regular virus transcribes DNA into RNA. (:
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 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.
What enzyme manufactures DNA that is complementary to a virus's RNA?
The enzyme that manufactures DNA complementary to the virus's RNA is called reverse transcriptase. Reverse transcriptase converts the viral RNA into DNA, which can then be integrated into the host cell's genome. This process is a key step in the replication cycle of retroviruses like HIV.
What enzyme do you need to get a copy of DNA from mRNA?
The enzyme needed to make a DNA copy of RNA (including mRNA) is called reverse transcriptase. This enzyme is capable of synthesizing a complementary DNA strand from an RNA template, which is the first step in generating a cDNA (complementary DNA) library.

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.
How does enzyme restriction limit the affect of a virus?
Enzyme restriction acts as a defense mechanism by cutting viral DNA at specific recognition sites, preventing the virus from replicating effectively in the host cell. This limits the virus's ability to spread and cause infection.
What enzyme is needed in order for transcription to take place?
RNA polymerase is the enzyme needed for transcription to take place. It catalyzes the synthesis of an RNA molecule from a DNA template.
The aids virus a retrovirus uses what to read RNA and synthesize the corresponding DNA?
An enzyme called Reverse transcriptase.
