Non-Coding Rna

 Non-coding Ribonucleic acid (ncRNA) is any class of RNA that is not translated into a polypeptide.  Non-coding RNAs may act as a biological catalysts, in which case they ae known as Ribozymes. The spliceosome is an example of a piece of biological catalytic machinery that uses ncRNA to catalyse the splicing of pre-mRNA. Another role of ncRNA is the  regulation gene control, which can be performed by promoting or inhibiting either transcription or translation.
