WebWhen mRNA forms a duplex with a complementary antisense RNA sequence, translation is blocked. This process is related to RNA interference. Cells can produce antisense RNA molecules naturally, called microRNAs, which interact with complementary mRNA molecules and inhibit their expression. Antisense RNAs can be classified in different ways. In terms of regulatory mechanisms, some authors group asRNAs into RNA-DNA interactions, RNA-RNA interactions either in nucleus or cytoplasm and RNA-protein interactions (epigenetic). Antisense RNAs can be categorized by the type of the promoters that initiate expression of asRNAs: independent promoters, shared bidirection… bishwambhar mishra google scholar
