title: Replication of DNA in UV-irradiated Escherichia coli in the absence of amino acids.
abstract: Since pyrimidine dimers are considered to be the cause of the synthesis of short DNA segments, normalization of DNA replication after UV irradiation should be in a temporal correlation with their removal. This correlation holds in exponentially growing excision-proficient Escherichia coli cells. However, when these cells are preincubated and postincubated without amino acids, synthesis of short segments continues although dimers are efficiently excised.
