title: Electron microscopic mapping of single-stranded discontinuities in cauliflower mosaic virus DNA by means of the biotin-avidin technique.
abstract: Biotin-labeled deoxyuridine triphosphate has been used to label the three natural single-stranded discontinuities of Cauliflower Mosaic Virus DNA. The presence of biotin permitted the direct visualization and mapping of the discontinuities by electron microscopy, using ferritin-labeled avidin.
