11. Concerning replication in E. coli: a. DNA polymerase I synthesizes Okazaki fragments. b. Polymerization of the leading strand DNA occurs 5' -> 3', but occurs 3' -> 5' on the lagging strand. c. DNA synthesis occurs at only one end of the replication bubble. d. Synthesis of the leading strand occurs continuously, while synthesis of the lagging strand occurs discontinuously. e. Okazaki fragment synthesis is primed by E. coli RNA polymerase.
