These were named hgc- ("high GC") A, B, C, D, E, F and G. Two other homologues were detected called HhcA and HhcB after "homologue of hgcC". A further RNA element, SscA RNA, was also identified.
Several RNA molecules were identified with the designation hgc- ("high GC") A through G. Furthermore, two other related molecules, HhcA and HhcB, which are homologues of hgcC, were discovered. Additionally, an RNA element named SscA was also isolated.
