EFFECT OF SILICA NANO-PARTICLES IN CONTROL OF MITE, Tetranychus cucurbitacearum (Sayed) AND AGRONOMIC TRAITS OF SOYBEAN PLANTS AND QUALITATIVE ASSESSMENT OF ITS GENOTOXICITY USING TOTAL PROTEIN AND RAPD ANALYSIS [PDF]

open access: yesJournal of Agricultural Chemistry and Biotechnology, 2015
Control of the two spotted spider mite, Tetranychus cucurbitacearum (Sayed) using conventional acaricides resulted in many problems. Thus, this study aimed to evaluate the effect of silica nano-particles (SiNPs) as a new approach to control spider mite ...

Stability of a stochastically perturbed model of intracellular single-stranded RNA virus replication

open access: yes, 2019
Replication of single-stranded RNA virus can be complicated, compared to that of double-stranded virus, as it require production of intermediate antigenomic strands that then serve as template for the genomic-sense strands.

Initiator tRNA genes template the 3\u27 CCA end at high frequencies in bacteria. [PDF]

open access: yes, 2016
BACKGROUND: While the CCA sequence at the mature 3\u27 end of tRNAs is conserved and critical for translational function, a genetic template for this sequence is not always contained in tRNA genes.

Protecting exons from deleterious R-loops: a potential advantage of having introns

open access: yesBiology Direct, 2007
Background Accumulating evidence indicates that the nascent RNA can invade and pair with one strand of DNA, forming an R-loop structure that threatens the stability of the genome. In addition, the cost and benefit of introns are still in debate.

Homologous Recombination: To Fork and Beyond [PDF]

open access: yes, 2018
Accurate completion of genome duplication is threatened by multiple factors that hamper the advance and stability of the replication forks. Cells need to tolerate many of these blocking lesions to timely complete DNA replication, postponing their repair ...
