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 generate complementary DNA (cDNA) from an RNA template, 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 ...
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).
10 de nov. de 2022 · Tools. Share. Graphical Abstract. Reverse transcriptases, enzymes that originally use RNA to write DNA, are featured in the review. They play important roles in modern research as well as diagnostics. Recent fields of activities include their tailoring, detection of RNA modifications or the reverse transcription of xeno-nucleic acids (XNAs).
13 de mar. de 2024 · reverse transcriptase, an enzyme encoded from the genetic material of retroviruses that catalyzes the transcription of retrovirus RNA (ribonucleic acid) into DNA (deoxyribonucleic acid). This catalyzed transcription is the reverse process of normal cellular transcription of DNA into RNA, hence the names reverse transcriptase and retrovirus.
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.
