WebTwo experiments with Xenopus laevis ribosomal DNA have demonstrated that in the base-paired sequence either both cytosines are methylated or neither is methylated. Half-methylated sites are not found. The first experiment involved reassociation of a labelled methylated ribosomal DNA restriction fragment (4.65-RI) with an excess of the … Webcladistics) grades pertain to polyphyly and paraphyly, and clades to monophyly. The origin of species or higher taxa by anagenesis, cladogenesis, or phylogen-esis, and persistence through stasis, is associated more with process biology in microevolution (see speciation processes) and particularly the assessment of patterns and rate of ...
