RNA as a Single strand flexible poly nucleotide molecule in the cell acts as a command book for the protein synthesis process. This molecule acts as a supervisor that controls different parts of the protein synthesis process by shaping a unique conformation and binding to different active sites.
RNA plays an important role in transferring and transforming information to the Protein structure and functions that handle our life.
RNAs also run a regulatory process to increase or decrease bio-processes in the cell. For this purpose they will bind directly to the regulatory elements on the gene and chromosome or handle the process by downstream products called protein that can be an enzyme or a regulatory protein.
