Small rna function
Small RNA (sRNA) are polymeric RNA molecules that are less than 200 nucleotides in length, and are usually non-coding. RNA silencing is often a function of these molecules, with the most common and well-studied example being RNA interference (RNAi), in which endogenously expressed microRNA (miRNA) or exogenously derived small interfering RNA (siRNA) induces the degradation of complementary messenger RNA. Other classes of small RNA have been identified… WebOur exploration of the physiological functions of probiotic bacteria hopes to elucidate the role of small regulatory RNAs or non-coding RNAs in regulating gene expression within the human body. The goal of this project was to identify and explore the conservation of function and structure of the sRNA, UspS, in two probiotic bacteria and to ...
