Select one: a. The two strands form continuously, catalyzed by DNA polymerase. b. The two strands form continuously, catalyzed by DNA ligase. c. One strand forms continuously, the other forms in short segments spliced by DNA polymerase. d. One strand forms continuously, the other forms in short segments spliced by DNA ligase. This answer is correct; they cannot both form continuously because of the antiparallel orientation of the two strands. Feedback The correct answer is: One strand forms continuously, the other forms in short segments spliced by DNA ligase.
