when replication was performed with dna polymerase iii* supplemented with increasing quantities of purified beta 2 subunit , the cycling time on uv-irradiated dna decreased from 14.8 min at 1.7 nm beta 2 down to 6 min at 170 nm beta 2 , a concentration in which beta 2 was in large excess over the polymerase .
