EXTRACTION AND MODIFICATION OF MACROALGAL POLYSACCHARIDES FOR CURRENT AND NEXT-GENERATION APPLICATIONS


Changes in both trans- and cis-regulatory elements mediate insecticide resistance in a lepidopteron pest, Spodoptera exigua.

The evolution of insect resistance to insecticides is frequently associated with overexpression of one or more cytochrome P450 enzyme genes.Although 355 maybelline fit me overexpression of CYP450 genes is a well-known mechanism of insecticide resistance, the underlying regulatory mechanisms are poorly understood.Here we uncovered the mechanisms of

G-Quadruplexes at Telomeres: Friend or Foe?

Telomeres are DNA-protein complexes that cap and protect the ends of linear chromosomes.In almost all species, telomeric DNA has a G/C strand bias, and the short tandem repeats of here the G-rich strand have the capacity to form into secondary structures in vitro, such as four-stranded G-quadruplexes.This has long prompted speculation that G-quadru
