Ribosomal RNA<span> (rRNA) associates </span>with<span> a set of </span>proteins<span> to form ribosomes. These complex structures, which physically move along an mRNA </span>molecule<span>, catalyze the assembly of amino acids into </span>protein<span> chains. They also bind tRNAs and various accessory </span>molecules<span> necessary for </span>protein<span> synthesis.</span>
