to determine whether the extent of transcription of different dna sequences is related to the order in which these sequences are replicated , i have selectively labelled early- and late-replicating dna with [ 3h ] thymidine ( [ 3h [ tdr ) and determined the extent to which the 3h-labelled non-repeated sequences of each dna preparation are hybridized by increasing concentrations of rna from exponentially growing kb cells .
