Example sentences for: double-stranded
How can you use “double-stranded” in a sentence? Here are some example sentences to help you improve your vocabulary:
RNA interference (RNAi), mediated by short interfering double-stranded RNA molecules (siRNA or dsRNA), is now recognized as a major mechanism of post-transcriptional gene silencing (PTGS) in essentially all eukaryotes [ 16 ] . Recently, the technique has been successfully applied to cultured mammalian cells, whereby introduction of 21-nucleotide long synthetic dsRNA molecules corresponding to specific mRNA sequences effectively and specifically degraded the cognate mRNAs and abrogated the expression of the corresponding proteins [ 17 18 ] . This prompted us to test a similar approach to knockdown PfPP1 function in the erythrocytic P. falciparum stages.
2% of all submitted bases are double-stranded and 48% of clones had complete double-stranded coverage.
In contrast to the ubiquitous DDRP, cellular RDRPs that are involved in PTGS so far have been detected only in eukaryotes [ 1 26 ] . The PTGS phenomenon covers a variety of complementarity-dependent silencing pathways, such as RNA interference (RNAi) in animals and slime mold, co-suppression (silencing of transgene and the corresponding endogenous genes) and virus gene resistance in plants, and quelling in fungi, all of which share a common mechanism of RNA turnover [ 28 37 38 39 40 ] . Essentially, double-stranded (ds) RNA, which is formed in these processes, triggers the activation of a sequence-specific RNA degradation system, which targets homologous RNAs [ 41 42 ] . The dsRNA is broken down by the Dicer enzyme into 21-25 nucleotide (nt) fragments called small interfering RNA or siRNAs [ 43 44 45 ] . The siRNAs subsequently associate with a complex of proteins called RISC and target homologous RNA by serving as guides for multiple rounds of RNA cleavage [ 45 46 ] .
In this communication, we establish 21-nucleotide long double-stranded interfering RNA as a viable tool to ablate specific cytoplasmic RNAs, as exemplified by the mRNAs of a RNA virus.
This reaction involves passage of another double-stranded DNA circle, instead of the complementary DNA strand through the break generated by DNA cleavage so the ZD domain would not be expected to play any significant role.
