Dna directed dna polymerase
WebDNA polymerase alpha also known as Pol α is an enzyme complex found in eukaryotes that is involved in initiation of DNA replication. The DNA polymerase alpha complex consists of 4 subunits: POLA1, POLA2, PRIM1, and PRIM2. [2] Pol α has limited processivity and lacks 3′ exonuclease activity for proofreading errors.

Reverse transcriptase (RT), also known as RNA-dependent DNA polymerase, is a DNA polymerase enzyme that transcribes single-stranded RNA into DNA. This enzyme is able to synthesize a double helix DNA once the RNA has been reverse transcribed in a first step into a single-strand DNA.
WebDNA polymerase theta is an enzyme that in humans is encoded by the POLQ gene. This polymerase plays a key role in one of the three major double strand break repair pathways: theta-mediated end joining (TMEJ). Most double-strand breaks are repaired by non-homologous end joining (NHEJ) or homology directed repair (HDR). However, in ... WebDNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Common component of RNA polymerases I and III which synthesize ribosomal RNA precursors and small RNAs, such as 5S rRNA and tRNAs, respectively. ... 2.170.120.12 DNA-directed RNA polymerase, insert domain 1 …
