Molecular cloning and characterization of the alkB gene of Escherichia coli

Using methods of in vitro recombination we constructed hybrid plasmids that can suppress the increased methylmethane sulfonate sensitivity caused by alkB mutation. Since the cloned DNA fragment was mapped at 47 min on the Escherichia coli K12 genetic map, an area where the alkB gene is located, we concluded that the cloned DNA fragment contains the alkB… CONTINUE READING
