Reverse transcriptase is the viral enzyme responsible for making a DNA copy of the RNA genome from a retrovirus. As such, it is technically known as an RNA-dependent DNA polymerase. This is opposite to the usual flow of genetic information from DNA to RNA to protein. This allows a virus with an RNA genome to make copies of itself that can be integrated into the DNA of its host.
What else can I help you with?
What enzyme do viruses use to produce m-RNA?
reverse transcriptase
Can reverse transcriptase be denatured?
Yes, reverse transcriptase can be denatured under certain conditions. High temperature or extreme pH levels can disrupt the structure of reverse transcriptase, rendering it inactive. Denaturation of reverse transcriptase can prevent it from catalyzing the conversion of RNA into DNA during the process of reverse transcription.
Which is the enzyme that HIV uses to synthesize DNA on an RNA template?
The enzyme that HIV uses to synthesize DNA on an RNA template is called reverse transcriptase. It catalyzes the conversion of viral RNA into DNA, which is an essential step in the HIV replication cycle.
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.
What is thepurpose of using reverse transcriptase?
To make DNA from mRNA
What are transcriptase inhibitors?
Substances that inhibit the production or the action of transcriptase, which is an enzyme.
What does transcriptase use to form DNA?
Reverse transcriptase use mRNA to form DNA. mRNA
What enzyme do viruses use to produce m-RNA?
reverse transcriptase
Can reverse transcriptase be denatured?
Yes, reverse transcriptase can be denatured under certain conditions. High temperature or extreme pH levels can disrupt the structure of reverse transcriptase, rendering it inactive. Denaturation of reverse transcriptase can prevent it from catalyzing the conversion of RNA into DNA during the process of reverse transcription.
What does a eukaryotic cell use to make reverse transcriptase?
A eukaryotic cell uses its own enzymes to make reverse transcriptase.
What enzyme is contained in retroviruses?
Retroviruses contain an enzyme called reverse transcriptase, which helps transcribe the viral RNA genome into DNA once inside the host cell. This DNA then integrates into the host cell's genome, allowing the virus to replicate and persist within the host.
What enzyme is unique to retrovirus?
Reverse transcriptase.
Retroviruses such as HIV contains what enzyme that enables DNA to be synthesized from rna?
Retroviruses such as HIV contain the enzyme called reverse transcriptase, which enables the synthesis of DNA from RNA. This DNA integrates into the host cell genome, allowing the virus to replicate and persist in the host.
Which is the enzyme that HIV uses to synthesize DNA on an RNA template?
The enzyme that HIV uses to synthesize DNA on an RNA template is called reverse transcriptase. It catalyzes the conversion of viral RNA into DNA, which is an essential step in the HIV replication cycle.
What enzyme is used in reverse transcription?
Reverse transcriptase is the enzyme used in reverse transcription to generate complementary DNA (cDNA) from an RNA template.
Which is a unique macromolecule present in certain viruses that is a target for antiviral agents a. DNA b. RNA c. reverse transcriptase d. ribosomes?
Reverse transcriptase.
What are non-nucleoside reverse transcriptase inhibitors?
delavirdine (Rescriptor), loviride, and nevirapine (Viramune) act by binding directly to the reverse transcriptase molecule, inhibiting its activity.
