Do sister forks of bidirectionally growing replicons proceed at unequal rates?
DNA fibre autoradiography in different tissues of the rodents Bandicota bengalensis and Nesokia indica reveals a high frequency of such bidirectionally replicating replicons whose sister 'hot' tracks are of unequal size. These results suggest intrarepliconic difference in the rates of fork migration in the two directions.
