Effect of Xenopus laevis oocyte extract on supercoiled simian virus 40 DNA: formation of complex DNA

D Gandini Attardi et al. Proc Natl Acad Sci U S A. 1976 Feb.

Abstract

A soluble cell-free extract derived from stage 6 Xenopus laevis oocytes is described. From supercoiled simian virus 40 DNA the extract produces nicked circles (having a single-strand scission), linear molecules of full unit size, shorter length fragments, and various forms of complex DNA.
