title: Electron microscope analysis of partial denaturation of F factor deoxyribonucleic acid.
abstract: Partial denaturation pattern of sex factor deoxyribonucleic acid of Escherichia coli was studied by electron microscopy. Clustering of the adenine-plusthymine-rich regions in one part of the molecule was revealed. The positions of these regions were located on the physical map of F by analyzing the partial denaturation pattern of heteroduplexes between F and F-prime factors with various parts of F sequences deleted.
