WebFeb 15, 1998 · The sliding clamp is left behind assembled around the duplex DNA. During lagging strand synthesis, a new sliding clamp is needed for the synthesis of each Okazaki fragment. Ten times more Okazaki fragments are formed during replication than the number of sliding clamps present within the cell, therefore, clamps must also be recycled. WebOne is a protein called the sliding clamp, which holds DNA polymerase III molecules in place as they synthesize DNA. The sliding clamp is a ring-shaped protein and keeps the DNA polymerase of the lagging strand from floating off when it re-starts at a new Okazaki … In E. coli this exonuclease activity is performed by DNA polymerase I. 3) … fatih atik gazeteci
