WebbSpecially engineered ribozymes will probably be used as gene shears to destroy such RNA molecules as produce harmful or undesirable properties in certain organisms. In particular, it is hoped that gene shears, by cutting and destroying virus RNA, will protect organisms against viral infections. WebbI develop and apply computational and modeling approaches to understand the structure/function relationships of RNAs at different levels of complexity and representations (sequence, 2D, and 3D structure). My research interests include RNomics (identification and characterization of non-coding RNA genes), computational …

Webb31 okt. 2024 · We also found RNA-silencing is induced on introduction of catalytically active as well as inactive ribozymes. Using RNA-silencing suppressors (RSS), we demonstrate that the endonucleolytic activity of ribozymes is a true phenomenon, even while a mutated version may demonstrate a similar down-regulation of the target RNA.

WebbThis technique is based on a correlation between the length of ion-paired oligomers and their retardation during HPLC. The advantages of reverse-phase ion-pair HPLC on polystyrene resin for the fast purification of oligoribonucleotides are discussed and illustrated through the examples of synthesized chimeric ribozymes. WebbThe ribozyme then dissociates from the cleaved substrate RNA, and repeatedly hybridizes to and cleaves additional substrate RNA molecules. Problems being addressed as this technology evolves involve optimization of ribozyme: substrate binding efficiencies and their effective transmission into cells. Webb9 feb. 2024 · Because efficient prebiotic pathways for RNA aminoacylation have not yet been elucidated, we utilized an aminoacylating ribozyme (flexizyme) ( 34) to generate aminoacylated RNA building blocks for ligation.

Webb28 feb. 2024 · Ribozymes are hybrid RNA molecules that break down the specifically targeted RNA. They hybridize with the target RNA to reveal a single secondary structure. Once the target has been disrupted, the ribozyme detaches from the disrupted transcript. The mechanism continues by binding the ribozyme to another RNA molecule. Webb1 apr. 2024 · Discussions on the status of definitions of life have long been dominated by a position known as definitional pessimism.
