During the process of replication, the polymerase enzyme starts the base synthesis as connected with the primers. these primers are then subsequently removed after replication. Remember that the lagging strand makes use of multiple primers as the polymerase enzyme can only synthesize polynucleotides in the 5' to 3' direction. On the other hand, the leading strand only requires a single primer and it is expected to synthesize complementary strands up to the very last base.
