extinction génique post-transcriptionnelle

OBS: PTGS : Bien qu'issue de l'expression anglaise «Post Transcriptional Gene Silencing», cette abréviation est utilisée dans les textes français.

CONT: Using this knowledge, an emerging use of PTGS and, in particular, RNA interference (RNAi), the initiating of PTGS by introducing small (21-25 nucleotides) double-stranded RNA (siRNA), as a tool to knock out the expression of specific genes in a variety of organisms can be observed.
OBS: Epigenic silencing of transgene and endogenous genes can occur at the transcriptional level (TGS) or at the post-transcriptional level (PTGS).
OBS: post-transcriptional silencing: Elliptical form of ""post-transcriptional gene silencing."" As the term ""silencing"" can only apply in this context to genes, the term ""gene"" can be removed.
