- Open QuestionAnalyze the following statements about DNA synthesis. Select True or False for each statement.T/FAn RNA polymerase is essential for DNA synthesis.T/FOkazaki fragments would be unnecessary if DNA polymerase could synthesize DNA in both the 3'→5' and 5'→3' directions.T/FDNA ligase is used more frequently on the lagging strand than on the leading strand.T/FToposiomerase is required to separate the two strands of DNA at the replication fork.
