One method of gene suppression is through antisense oligonucleotides (ASOs). ASOs are small single-stranded chemically modified DNA molecules that use Watson Crick base pairing to bind RNA and catalyze downstream events . Gene suppressing ASOs form DNA/RNA heteroduplexes when bound, recruiting RNase H to degrade the targeted transcript. ABSTRACT. Non-coding transcription across the antisense strands of genes is an abundant, pervasive process in eukaryotes from yeast to humans, however its biological function remains elusive. Here, we provide commentary on a recent study of ours, which demonstrates a genome-wide role for antisense transcription: establishing a unique, dynamic Antisense oligonucleotide (ASO) chemical structures. Schematic of unmodified DNA/RNA base pair (left). Different backbone modifications that can be applied (top row) and different 2’-sugar modifications that can be used (bottom row) to increase nuclease resistance and RNA binding affinity of the ASO. Study with Quizlet and memorize flashcards containing terms like The use of microorganisms to produce useful products is known as A) biotechnology. B) gene modification. C) genomics. D) recombinant DNA technology. E) cloning., In the 20th century, scientists harnessed the natural metabolic reactions of bacteria to make ________ for the first time in an industrial setting. A) soy sauce B The goal of the antisense approach is the downregulation of a molecular target, usually achieved by induction of RNase H endonuclease activity that cleaves the RNA-DNA heteroduplex with a significant reduction of the target gene translation (Figure 1).
