Preparation and isolation of covalently closed circular rDNA molecules from DNA of Xenopus laevis.
We describe a method leading to the formation of closed circles of rDNA starting from total DNA of Xenopus laevis. Linear DNA molecules were digested with exonuclease 3 and self-annealed. Open circles were enriched and covalently closed by the simultaneous use of polynucleotide kinase, DNA polymeras...
