the extent of homology between the nucleotide sequence of l-rrna ( the major rna component of the larger ribosomal subparticle ) of a lower eukaryote ( neurospora crassa ) and an amphibian ( xenopus laevis ) was investigated by utilizing rdna ( dna coding for rrna ) of x. laevis cloned in plasmids pmb9 and pml2 , and rdna of n. crassa cloned in bacteriophage lambda .
