title: Properties of a deoxyribonucleic acid ligase mutant of Escherichia coli: x-ray sensitivity.
abstract: A deoxyribonucleic acid ligase-deficient mutant is X-ray sensitive relative to the parent strain, suggesting that deoxyribonucleic acid ligase functions in repair of X-ray-induced, single-strand scissions.
