Answer #1

The option D is the right choice. The enzyme repaid damage in DNA as well as replace the RNA fragments in lagging strand of DNA with DNA fragments. The main involvement of DNA polymerase 1 is reffered to proofreading. Helicase enzyme is involved in unwinding of DNA strand for initiation of replication. DNA ligase enzyme helps in joining of short fragments of DNA in okazaki fragments. Primase catalyse the synthesis of RNA primers with which the DNA polymerase enzyme can synthesis DNA daughter strand in lagging strands.
