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…
