Transcriptase in Biological Definition

Retrovirus

... plus sense RNA molecules. It relies on reverse transcriptase to perform a kind of reverse transcription of ... thought to only occur from DNA to RNA, reverse transcriptase transcribes RNA into DNA. The term "retro" in ... the Central dogma of molecular biology . Reverse transcriptase activity outside of retroviruses has been found ...

Enzyme

... group from an amino acid residue of a protein Restriction enzymes : those enzymes which cut DNA or RNA at specific locations Reverse transcriptase : used by retroviruses to transcribe information from RNA into DNA Ribulose bisphosphate carboxylase : fixes carbon in green plants. ...

Gene therapy

... a DNA copy from an RNA molecule is termed reverse transcription . It is carried out by one of the enzymes carried in the virus, called reverse transcriptase . After this DNA copy is produced and is free in the nucleus of the host cell, it must be incorporated into the genome of the host cell. That is, ...

Hepadnaviridae

... . They have a peculiar mode of replication, because they replicate through an RNA intermediate (which they translate back into DNA using reverse transcriptase ). Because of this mode of replication, Hepadnaviruses are classified as RNA viruses . ...

Hepatitis B

... nucleocapsid (core) enclosing a circular, double-stranded DNA genome. The virus is unique amongst the DNA viruses in that it uses a reverse transcriptase to generate the genomic DNA to deliver to its progeny. Additionally, the DNA genome is incomplete on one strand. Hepatitis D infection requires a ...

Lytic cycle

... into messenger RNA (mRNA) molecules that are then used to direct the ribosome. In retroviruses , or RNA viruses, a unique enzyme called reverse transcriptase transcribes the viral RNA into DNA, which is then transcribed again into mRNA. Replication and lysis After many virus copies are made, they ...

Virus

... to make hundreds of duplicates of the original RNA. A second group of RNA-containing viruses, called the retroviruses , uses the enzyme reverse transcriptase to synthesize a complementary strand of DNA so that the virus's genetic information is contained in a molecule of DNA rather than RNA. The viral DNA ...
