reverse transcription

reverse transcription

n.

The process by which DNA is synthesized from an RNA template.

---

transcription

the synthesis of an RNA copy from a nucleotide sequence in a limited region of DNA. See also deoxyribonucleic acid and transcriptase.

---

transcription-control region

the cis-acting DNA sequences regulating transcription of a specific gene.

transcription factor (TF)

a general term for any protein, other than RNA polymerase, required to initiate or regulate transcription in eukaryotic cells. General TFs are involved in the formation of the transcription-preinitiation complexes near the start site and are required for transcription of all genes; specific TFs stimulate (activators) or inhibit (suppressors) transcription of particular genes by binding to their regulatory sequences.

nested set transcription

a hallmark of the replication strategy of coronaviruses, toroviruses and arteriviruses, in which a nested set of subgenomic mRNAs are generated having identical 5′-leader sequences and a common 3′-termini, but because of discontinuous transcription each mRNA has a unique coding sequence and is transcribed into a unique viral protein.

reverse transcription

the synthesis of a DNA copy from a RNA template, catalyzed by reverse transcriptase.

transcription unit

see operon.
