Abstract
A recombinant plasmid, pMQ3, carrying the dam gene of Escherichia coli K-12, was constructed and transformed into dam+ and dam- strains. Both dam- and dam+ strains containing pMQ3 showed a wild phenotype for all traits, including mutation rate, except for a 10-fold increase in DNA adenine methylase activity.
