Gene Activation and Gene Silencing [PDF]
Plant Physiology, 2001 Twenty-five years ago the field of eukaryotic gene regulation was in its infancy. Paradigms driving experiments came primarily from work with prokaryotes and the phage that infected them (12). These paradigms, pioneered by Jacob and Monod, were that genes contained promoter sequences to which ...

BMJ, 2003 To the Medical Research Council, currently enjoying the warmth of celebrations marking the 50th anniversary of Crick and Watson's discovery of the double helix at an MRC laboratory, last week's report by the House of Commons science and technology committee must have felt like a bucket of ice cold water.

Gene Dosage and Gene Duplicability [PDF]
Genetics, 2008 Abstract The evolutionary process leading to the fixation of newly duplicated genes is not well understood. It was recently proposed that the fixation of duplicate genes is frequently driven by positive selection for increased gene dosage (i.e., the gene dosage hypothesis), because haploinsufficient genes were reported to have more ...

Enhanced collective Purcell effect of coupled quantum emitter systems
, 2019 Cavity-embedded quantum emitters show strong modifications of free space radiation properties such as an enhanced decay known as the Purcell effect. The central parameter is the cooperativity $C$, the ratio of the square of the coherent cavity coupling ...

Genetic basis for nitrate resistance in Desulfovibrio strains
Frontiers in Microbiology, 2014 Nitrate is an inhibitor of sulfate-reducing bacteria (SRB). In petroleum production sites, amendments of nitrate and nitrite are used to prevent SRB production of sulfide that causes souring of oil wells.

Transmissive optomechanical platforms with engineered spatial defects
, 2014 We investigate the optomechanical photon-phonon coupling of a single light mode propagating through an array of vibrating mechanical elements. As recently shown for the particular case of a periodic array of membranes embedded in a high-finesse optical ...

Protected state enhanced quantum metrology with interacting two-level ensembles
, 2013 Ramsey interferometry is routinely used in quantum metrology for the most sensitive measurements of optical clock frequencies. Spontaneous decay to the electromagnetic vacuum ultimately limits the interrogation time and thus sets a lower bound to the ...

Cloning and characterisation of the S.pombe rad15 gene, a homologue to the S.cerevisiae RAD3 and human ERCC2 genes [PDF]
, 1992 The RAD3 gene of Saccharomyces cerevisiae encodes an ATP-dependent 5' - 3' DNA helicase, which is involved in excision repair of ultraviolet radiation damage.
