Unformatted text preview: as a template. → Topoisomerase : relieves strain in DNA’s double helix by breaking, swiveling, and rejoining DNA strands ahead of the replication fork. 3. Why are RNA primers necessary in replication? → RNA primers are required to begin DNA replication. 4. What purpose do Okazaki fragments serve in the process of replication on the lagging strand? → Okazaki fragments are produced because of the need for DNA polymerase to always synthesize in a 5′ to 3′ direction resulting in a long, continuous strand of DNA. 5. How are Okazaki fragments converted into a continuous strand of DNA? → DNA ligase joins all the sugar-phosphate backbones of the Okazaki fragments into one continuous strand of DNA. 1...
