Clusters of microbubbles, represent probable sites of newly initiated DNA synthesis, were identified in nuclear DNA from Physarum polycephalum by using the electron microscope. Their presence is associated specifically with S-phase. Each microbubble corresponds in size to a replicating segment of DNA about 100-5000 nucleotide residues in length. The DNA structures containing microbubbles are metastable, and revert to native DNA in the presence of moderate concentrations of formamide used to prepare samples for electron microscopy. It is suggested that each cluster of microbubbles may correspond to a unit of replication (a replicon) in Physarum DNA.

Feulgen microspectrophotometry was performed using the two wavelength method on 33 lesions and showed that five of ten carcinomas and 12 of 16 leukoplakias had diploid cell lines. This correlates well with similar findings in cervical cancer and dysplasia suggesting that changes in nuclear deoxyribonucleic acid content occur quite early in the evolution of cancer.
