the results show that ( i ) the functional origin of replication colocalizes with an autonomously replicating sequence element previously mapped to the nontranscribed spacer region , ( ii ) only a fraction of the potential origins are utilized in a single s phase , and ( iii ) the replication forks moving counter to the direction of transcription of the 37s precursor rna stop at or near the termination site of transcription .
