Preparation of Phi29 DNA polymerase free of amplifiable DNA using ethidium monoazide, an ultraviolet-free light-emitting diode lamp and trehalose. [PDF]
We previously reported that multiply-primed rolling circle amplification (MRPCA) using modified random RNA primers can amplify tiny amounts of circular DNA without producing any byproducts.

First-passage problems in DNA replication: effects of template tension on stepping and exonuclease activities of a DNA polymerase motor [PDF]
A DNA polymerase (DNAP) replicates a template DNA strand. It also exploits the template as the track for its own motor-like mechanical movement. In the polymerase mode it elongates the nascent DNA by one nucleotide in each step. But, whenever it commits an error by misincorporating an incorrect nucleotide, it can switch to an exonuclease mode.

Stochastic resetting in backtrack recovery by RNA polymerases [PDF]
Transcription is a key process in gene expression, in which RNA polymerases produce a complementary RNA copy from a DNA template. RNA polymerization is frequently interrupted by backtracking, a process in which polymerases perform a random walk along the DNA template.

DNA Polymerase Profiling [PDF]
We report a simple homogeneous fluorescence assay for quantification of DNA polymerase function in high throughput. The fluorescence signal is generated by the DNA polymerase triggering opening of a molecular beacon extension of the template strand. A resulting distance alteration is reported by fluorescence resonance energy transfer between two dyes ...

Fidelity of DNA polymerases in the detection of intraindividual variation of mitochondrial DNA
Here we investigated the consequences of PCR amplification errors in the identification of intraindividual mtDNA variation. The bumblebee Bombus morio was chosen as model for the COI gene amplification tests with two DNA polymerases (Taq and Q5 ...
