Detailed explanation-1: -Post-transcriptional gene silencing (PTGS) is one mechanism that degrades specific messenger RNAs and thereby reduces the expression of a specific gene. PTGS has many names: cosuppression in plants, quelling in fungi and RNA interference in animals, but in all cases, degraded mRNA decreases gene expression.
Detailed explanation-2: -For example, each dsRNA is cleaved into small pieces by the DICER enzyme. These pieces are called short interfering RNAs (siRNAs) and are about 20 to 25 nucleotides in length. Similar to miRNA, siRNA binds to RISC and cleaves targeted sequences of mRNA.
Detailed explanation-3: -Flavr Savr tomatoes are an example of gene silencing. Tomatoes tend to have a short shelf life because they ripe very soon. To slow down the ripening process, the gene silencing method was introduced in their genome.
