La transcriptasa inversa (también, transcriptasa reversa, retrotranscriptasa) es una enzima de tipo ADN polimerasa que tiene como función sintetizar ADN de doble cadena utilizando como molde ARN monocatenario, es decir, catalizar la retrotranscripción o transcripción inversa. Se encuentra presente en los retrovirus.
A reverse transcriptase (RT) is an enzyme used to convert RNA genome to DNA, a process termed reverse transcription. Reverse transcriptases are used by viruses such as HIV and hepatitis B to replicate their genomes, by retrotransposon mobile genetic elements to proliferate within the host genome, and by eukaryotic cells to extend the ...
Los inhibidores de la transcriptasa inversa son fármacos que inhiben a la polimerasa de ADN dependiente de ARN y codificada por el VIH que convierte al ARN vírico en ADN provírico, que luego se incorpora en un cromosoma de la célula hospedadora. Esta polimerasa es conocida también como transcriptasa inversa.
Reverse transcription polymerase chain reaction (RT-PCR) is a laboratory technique combining reverse transcription of RNA into DNA (in this context called complementary DNA or cDNA) and amplification of specific DNA targets using polymerase chain reaction (PCR).
Telomerase reverse transcriptase (abbreviated to TERT, or hTERT in humans) is a catalytic subunit of the enzyme telomerase, which, together with the telomerase RNA component (TERC), comprises the most important unit of the telomerase complex. Telomerases are part of a distinct subgroup of RNA-dependent polymerases.
These RNA-encoded viruses have a phase in their life cycle in which their genomic RNA is converted back to DNA by a virally-encoded enzyme known as reverse transcriptase. The ability to convert RNA to DNA is a method that is desirable in the laboratory for numerous reasons.
1 de ene. de 2021 · The simultaneous discovery in 1970 of reverse transcriptase in virions of retroviruses by Howard Temin and David Baltimore was perhaps the most dramatic scientific moment of the second half of the 20th century.
