- 1966 Scientist Kiwako Sakab and Reiji Okazaki discovered fragments, now known as Okazaki fragments, during their research on DNA replication of Escherichia coli. They continued their research studying bacteriophage DNA replication in Escherichia coli. Which enzyme is used during replication to attach Okazaki fragments to each other? A: DNA ligase B: DNA polymerase C: RNA polymerase D: reverse transcript
