What is a non-retroviral virus?
Retroviruses are a class of RNA virus that use Reverse transcription to convert their RNA to DNA for their infection.
Why retro virus is RNA virus?
Because retro virus has only RNA as genetic material. Its replication is in reversal order known as Reverse Transcriptase.
What is Replication of an RNA virus?
You might be referring to the reverse-transcription that many retroviruses use (a virus with an RNA that turns into DNA). By using the enzyme reverse transcriptase, viruses like HIV can make a DNA from RNA template.
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.
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 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.
Is reverse transcriptase a virus or bacteria?
Reverse transcriptase is an enzyme found in retroviruses, which are a type of virus. It plays a key role in converting the virus's RNA genome into DNA for integration into the host cell's genome.
How nucleic acids form?
they are constructed from individual nucleotides by enzymes called transcriptases on an existing nucleic acid template. The types of transcriptases are:DNA transcriptase - copies DNA prior to cell divisionRNA transcriptase - copies DNA to mRNAreverse transcriptase - used by some RNA viruses to copy their RNA to DNA
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.
What would the HIV viral sequence of AUCUU be converted to and by what enzyme?
The HIV virus is an RNA virus, so you know the sequence AUCUU is the RNA sequence. (You also know it is RNA because it contains uracil.) HIV is a retrovirus, so its RNA will be transcribed to DNA by the enzyme reverse transcriptase and then inserted into the host's genome. The RNA sequence of AUCUU would be transcribed to TAGTT.
How is retrovirus different from DNA virus?
Retro virus has reverse transcription in its replication cycle. In other words, rna is template for synthesis of dna. With dna virus, there is no reverse transcription in the replication cycle. Dna is the template for dna synthesis.
