Inside a living cell coexist 2 different groups of nucleic acids: DNA and RNA. It is well-known that DNA is very important because it holds all the genetic information necessary to make a whole living organism; however, RNA, which is a transcriptional copy of the DNA, is much less known but also plays a very important role in maintaining life: it performs multiple functions within the cell and without it, no proteins could be synthesized. A riboswitch is a regulatory element present in some mRNA that regulates gene expression in response to specific chemical signals; they act as switches, turning the genes ON or OFF depending on the physical conformation of the riboswitch. Since their architecture and regulation mechanism are relatively simple, they can be engineered to respond to a wide range of molecules of interest; this makes riboswitches attractive gene regulatory devices for synthetic biology applications such as artificial cells.
