By tethering RNA polymerase with the coupling transcription factor NusG or its paralog or version, RfaH, which threads the ...

polymerase chain reaction / PCR Polymerase chain reaction, or PCR, is a laboratory technique used to make multiple copies of a segment of DNA.

A breakthrough enzyme aims to resolve a persistent DNA artifact that has challenged forensic analysis for decades.

Researchers show that polymerase theta can efficiently convert RNA sequences back into DNA, a feat more common in viruses than eukaryotic cells.

New study shows RNA polymerase I halts at abasic DNA damage, helping prevent faulty rRNA production and exposing lesions for repair in dividing cells.
