Both … WebA ribotype is essentially an RFLP consisting of the restriction fragments from a particular genome, which contain rRNA genes. To obtain a ribotype for an organism, it must first be cultured to obtain enough cells for the procedure. Total DNA is then isolated within the riboprinter and is totally restricted using a restriction enzyme.
