title: [Electron microscopic study of genome homology in 2 clones of the simian adenoviruses type 7].
abstract: Homology of the genomes of large-plaque (lp) and small-plaque (sp) clones of simian adenovirus type 7 (SV7) was studied experimentally. Guanidine chloride helped to isolate circular DNA molecules of identical length for both clones within the measurement error (1 = 11 +/- 0.2 micrometer). A heteroduplex SV7lp--SV7sp molecule was found to have two nonhomology sites 0.5 +/- 0.3 mu and 1.0 +/- 0.5 micrometer long located at a distance of 2 and 4 micrometer from one of the ends of the molecules, respectively.
