DNA PrimaseDNA ReplicationDNA SynthesissiRNAIn eukaryotic cells, DNA replication is carried out by the coordinated action of three DNA polymerases (Pols), Pol α, δ, and ε. In this report, we describe the reconstitution of the human four-subunit Pol ε and characterization of its catalytic ...
The single stranded DNA binding protein RPA plays a pivotal role in DNA replication. The archaeal RPA hosts a WH domain that interacts with the DNA primase and the replicative polymerase PolD. Here the authors provide a molecular understanding of the regulatory activity of archaeal RPA. Markel Ma...

In eukaryotes, DNA polymerases (Pols)3 α, δ, and ϵ jointly support DNA replication, and their overall roles in this process have been defined (1). The initiation of DNA replication is catalyzed by the Pol α-primase complex, composed of the Pol α complex (p180-p70) associated with ...
The best characterized of the enzymes is DNA polymerase, where it has been possible to assign a role in DNA replication to one specific form, polymerase‐α. With DNA polymerase‐α, there is also some information on regulatory mechanisms, and on subunit composition. By contrast, others of ...
During DNA replication, which strand is the lagging strand? Why can't both strands be synthesized in the same manner? What is topoisomerase? Describe its role in DNA replication. How can DNA be transcribed to RNA? What is the type of replication that DNA undergoes in order to be copied?
Primase | Definition, Types & Function from Chapter 11 / Lesson 8 35K What does primase do in DNA replication? In this lesson, see the primase definition, primase function, primase types, and the role of primase in DNA replication. Related...
these components together constitute the trombone model of DNA replication. The leading strand polymerase follows helicase, as the first lagging strand polymerase moves away from the fork. Helicase continues to generate single-strand DNA, and primase synthesizes a new primer. The clamp loader adds a...
