Adison Mahoney · Answer 1

Both leading and lagging strands

Explanation:

DNA replication is the enzyme of DNA replication that forms new DNA strands. However, the enzyme cannot start the process of synthesis of new DNA strands by itself but needs small primers. Primers are the small RNA sequences synthesized by RNA primase on both leading and lagging strands.

These primers are elongated by DNA polymerase by the addition of deoxyribonucleotides according to the sequence of the template strand. Since DNA replication on both lagging and leading strand is carried out by DNA polymerase, RNA primers are present on both lagging and leading strands.
