Cooperative base pair melting by helicase and polymerase positioned one nucleotide from each other

open access: yeseLife, 2015
Leading strand DNA synthesis requires functional coupling between replicative helicase and DNA polymerase (DNAP) enzymes, but the structural and mechanistic basis of coupling is poorly understood.

Page turning system [PDF]

open access: yes, 1992
A device for holding reading materials for use by readers without arm mobility is presented. The device is adapted to hold the reading materials in position for reading with the pages displayed to enable turning by use of a rubber tipped stick that is ...

Pairing Mechanism in Fe-Based Superconductors [PDF]

open access: yesAnnual Review of Condensed Matter Physics, 2012
I review recent works on the symmetry and the structure of the superconducting gap in Fe-based superconductors (FeSCs) and on the underlying pairing mechanism in these systems. The experimental data on superconductivity show very rich behavior, with potentially different symmetry of a superconducting state for different compositions of the same ...

PP2C – like promoter and its deletion variants are induced by ABA but not by MeJA and SA in Arabidopsis thaliana

open access: yesFrontiers in Plant Science, 2016
Gene expression is mediated through interaction between cis regulatory elements and its cognate transcription factors. Cis regulatory elements are defined as non-coding DNA sequences that provide the binding sites for transcription factors and are ...
