Download scientific diagram | 5 Pre-mRNA is transcribed from a gene. It is then processed through a carefully choreographed set of steps to the mature mRNA which is exported to the cytoplasm. These steps include 5' and 3' modifications, (5' cap: 3' poly A) splicing and specific transport activities. Numerous mechanisms of action for antisense drugs have been identified and they affect many steps post transcription and/or enhance cellular degradation of the RNA (Source: Kurreck, 2003). from publication: Gupta SM & Tomar NR (2012) “Antisense Technology”.
