title: Isolation and genetic analysis of a strain of Escherichia coli K-12 with an amber recA mutation.
abstract: The isolation, properties, and genetic analysis of a strain of Escherichia coli K-12 with an amber recA mutation are described. The experiments demonstrate that the recA product is a protein that is probably not essential for growth.
