Web11 Apr 2024 · Ribozyme-mediated RNA synthesis and replication in a model Hadean microenvironment Posted by Dan Breeden in categories: biological, chemistry, genetics, robotics/AI Zoom Enzyme-catalyzed replication of nucleic acid sequences is a prerequisite for the survival and evolution of biological entities. WebSince the initial discovery of catalytic RNAs, or ribozymes, various examples such as the twister ribozyme have been discovered. We hypothesized that part of the twister catalytic mechanism could be studied in isolation via RNA hexamers that were shown to cleave at UA or CA motifs, similar to twister. I found that these UA and CA motifs in small hexamers do …

Riboswitches are often conceptually divided into two parts: an aptamer and an expression platform. The aptamer directly binds the small molecule, and the expression platform undergoes structural changes in response to the changes in the aptamer. The expression platform is what regulates gene expression. Expression platforms typically turn off gene expression in response to the small molecule, but s…
Web31 Jan 2024 · The ribozyme used in this study is a truncated version (56 ribonucleotides) of the short R8-9 L1 ribozyme (74 ribonucleotides) . The annealing region of the DNA effector was removed to simplify the reaction scheme, thus reducing the number of ligation partners from three to two, namely, the truncated ribozyme body and its oligonucleotide substrate.
