Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis â the stitching together of amino acids to make a protein molecule. In fact, rRNA is sometimes called a ribozyme or catalytic RNA to reflect this function.
Nuclear Transport. Chapter 5. After RNA molecules (mRNA, tRNA and rRNA) are produced in the nucleus, they must be exported to the cytoplasm for protein synthesis. On the other hand, many proteins operating in the nucleus must be imported from the cytoplasm. The traffic through the nuclear envelope is mediated by a protein family which can be divided into exportins and importins. Binding of a molecule (a cargo) to exportins facilitates its export to the cytoplasm.
