Which of the following statement about eukaryotic DNA replication is INCORRECT?
Eukaryotes require two enzymes to remove RNA primers. Chromatin must be dismantled in advance of replication forks and reassembled on daughter strands after the fork has passed through. The same polymerase in humans is involved in proofreading and primer removal as well as lagging strand elongation. Only one DNA polymerase is required to propagate a replication fork. The main DNA polymerase that elongates the leading strand has an intrinsic processivity factor.Explanation / Answer
The correct option is Only one DNA polymerase is required to propagate a replication fork.
During the process of DNA replication, replication fork forms within the nucleus. It is propagated by helicases, which break the hydrogen bonds holding the two DNA strands together. These two strands act as the template for the leading and lagging strands, which are propagated by DNA polymerase.
