DNA fiber autoradiography has shown an increase in size of replicons during early development of the frog embryo. Replicons of endoderm cells were considerably larger than those of dorsal ectoderm and mesoderm cells in tailbud embryos. Late replicating DNA in partially synchronized tailbuds has a more rapid rate of replicon elongation than does early replicating DNA.
