Polymerase Mu Is a DNA-Directed DNA/RNA Polymerase [PDF]
DNA polymerases are defined as such because they use deoxynucleotides instead of ribonucleotides with high specificity. We show here that polymerase mu (pol μ), implicated in the nonhomologous end-joining pathway for repair of DNA double-strand breaks, incorporates both ribonucleotides and deoxynucleotides in a template-directed manner.

Profilin and formin constitute a pacemaker system for robust actin filament growth
The actin cytoskeleton drives many essential biological processes, from cell morphogenesis to motility. Assembly of functional actin networks requires control over the speed at which actin filaments grow. How this can be achieved at the high and variable

Translesion synthesis: Y-family polymerases and the polymerase switch
Replicative DNA polymerases are blocked at DNA lesions. Synthesis past DNA damage requires the replacement of the replicative polymerase by one of a group of specialised translesion synthesis (TLS) polymerases, most of which belong to the Y-family. Each of these has different substrate specificities for different types of damage.

Accessibility of DNA in Chromatin to DNA Polymerase and RNA Polymerase [PDF]
The accessibility of DNA in chromatin to both exogenous DNA polymerase and RNA polymerase is slight when compared to isolated DNA. DNA in extracted chromatin is somewhat more accessible to these enzymes than is DNA in the chromatin of isolated nuclei; and the DNA template of chromatin is more accessible to DNA polymerase than to RNA polymerase.

A reverse transcriptase ribozyme
A highly evolved RNA polymerase ribozyme was found to also be capable of functioning as a reverse transcriptase, an activity that has never been demonstrated before for RNA. This activity is thought to have been crucial for the transition from RNA to DNA

Noroviruses (the Caliciviridae family) are a common cause of acute gastroenteritis in all age groups. These small non-envelope viruses with a single-stranded (+)RNA genome are characterized by high genetic variability.

Single-peptide DNA-dependent RNA polymerase homologous to multi-subunit RNA polymerase [PDF]
Transcription in all living organisms is accomplished by multi-subunit RNA polymerases (msRNAPs). msRNAPs are highly conserved in evolution and invariably share a B400 kDa five-subunit catalytic core.

eDNA Replicates, Polymerase and Amplicon Size Impact Inference of Richness Across Habitats
Environmental DNA‐based monitoring has been increasingly used in the last decade to monitor biodiversity in aquatic and terrestrial systems. Molecular‐based surveys now allow quick and reliable production of baseline knowledge of species community ...

Hepatitis B virus (HBV) polymerase seems to be very hard to express and purify sufficiently, which has long hampered the generation of anti-HBV drugs based on the nature of the polymerase.
