Spontaneous mutations in the galactose operons of Streptomyces coelicolor A3 (2) and Streptomyces lividans 66.

Abstract excerpt

Mutations can be divided into two classes: point mutations (base changes, frame shifts) and DNA rearrangements (deletions, insertions, inversions etc.). In Escherichia coli K 12, DNA insertions account for up to 40% of spontaneous mutations that inactivate genes (for review, see CULLUM 1985) and...
