How do ribozymes inhibit translation
WebSep 14, 2014 · 6. Diff. between antisense technology & RNAi The intended effect in both will be same i.e. gene silencing but the processing is little but different. Antisense technology degrades RNA by enzymes RNaseH while RNAi employed the enzyme DICER to degrade the m RNA. RNAi are twice larger than the antisense oligonucleotide. 6. 7. WebJul 18, 2000 · to inhibit translation of a complementary RNA in a cell-free system in 1977 [1]. One year later, Zamecnik and Stephenson noted that a short (13nt) DNA oligonucleotide reverse complementary in sequence (antisense) to the Rous sarcoma virus could inhibit viral replication in culture [2]. This observation is credited as being among the first to sug-
