Unformatted text preview: as a template. Topoisomerase : relieves strain in DNAs 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...
