<P> Some RNA molecules play an active role within cells by catalyzing biological reactions , controlling gene expression , or sensing and communicating responses to cellular signals . One of these active processes is protein synthesis , a universal function where RNA molecules direct the assembly of proteins on ribosomes . This process uses transfer RNA ( tRNA ) molecules to deliver amino acids to the ribosome , where ribosomal RNA ( rRNA ) then links amino acids together to form proteins . </P>
