DNA RNA PROTEIN
(Ellington and Szostak, 1990)
Regulation by Transcriptional Termination
Regulation by Translational Initiation Inhibition
This type of gene expression is given different names in different organisms.
Self-cleaving RNAs can be placed under allosteric control by various small molecules, which can then be used to analyze the composition of chemical and biological mixtures .(Seetharaman et al, 2001)
RNA switches can be used in gene therapy, allowing the patient to take pills to switch introduced gene on or off.
An array of RNA molecular switches constructed using seven distinct effector-modulated ribozymes based on the hammerhead self-cleaving RNA.
