RNA processing

RNA processing is a crucial step in the flow of genetic information from DNA to proteins. After a gene in DNA is copied into a precursor messenger RNA (pre-mRNA), this pre-mRNA undergoes modifications. These include adding a protective cap at one end, a tail at the other, and removing non-coding regions called introns. The remaining coding regions, or exons, are then joined together. This mature messenger RNA (mRNA) is then ready to be translated into a protein, which performs various functions in the cell. Thus, RNA processing ensures that the correct information is conveyed for protein synthesis.
