The lagging strand uses many {{c1::primers}} because it is formed in fragments called {{c2::Okazaki}} fragments.

A diagram showing D N A replication. Separated double strand D N A is shown in black. The top black strand runs 3 prime to 5 prime and is attached to a leading strand that is growing from 5 prime to 3 prime due to D N A polymerase moving towards the 3 prime end of the leading strand. The 5 prime end of this strand is yellow and the remainder is blue. The bottom black strand runs 5 prime to 3 prime and is attached to the lagging strand, which consists of a pair of Okazaki fragments that run in the opposite direction. The 5 prime end of each of these fragments is yellow and the remainder of each fragment is blue. D N A polymerase moves towards the 3 prime end of the right hand Okazaki fragment and is nearing the gap between fragments.
