#Unit 3. Fundamental Processes

The two cores have different abilities to dissociate from DNA. This corresponds to the need to synthesize 

a continuous leading strand (where polymerase remains associated  with the template) and 

a discontinuous lagging strand (where polymerase repetitively dissociates and reassociates)
