ELECTRON MICROSCOPY OF SINGLE-STRANDED DNA: CIRCULARITY OF DNA OF BACTERIOPHAGE PHI-X174

D FREIFELDER et al. Science. .

Abstract

The single-stranded DNA of coliphage X174 has been examined with the electron microscope by a modification of the protein-monolayer-adsorption technique. The molecules were found to be circular with a total length of 1.77 +/- 0.13 microns.
