1. In prokaryotes, the lagging strand primers are removed by :

A) DNA polymerase I
B) DNA polymerase III
C) 3' to 5' exonuclease
D) DNA ligase

... Answer is B) DNA polymerase III

DNA polymerase III will then synthesize a continuous or discontinuous strand of DNA, depending if this is occurring on the leading or lagging strand (Okazaki fragment) of the DNA. DNA polymerase III has a high processivity and therefore, synthesizes DNA very quickly. This high processivity is due in part to the β-clamps that "hold" onto the DNA strands.
