Abstract:
MCS4 RNA is one of the small stable RNAs found in Mycoplasma capricolum. Its function is unknown. The conformation of MCS4 RNA (125 nucleotides in length) in solution was investigated using chemical and enzymatic probes. Single and double-stranded regions were estimated by means of diethyl pyrocarbonate (DEPC) and by dimethyl sulfate (DMS) modifications. Ribonuclease V1 was also used to identify paired or stacked nucleotides. Based on these data, a secondary structure model for MCS4 RNA containing four stem structures was constructed.

RNA Structure
The basic structure of RNA consists of a five-carbon sugar and one of four nitrogenous bases. Although most RNA is single-stranded, it can form complex secondary and tertiary structures. Such structures play essential roles in the regulation of transcription and translation.
