D)the holoenzyme
E)DNA gyrase

Quizplus · Accepted Answer

DNA ligase joins the last deoxyribonucleotide added during RNA primer digestion to the 5' end of the previously synthesized and adjacent DNA fragment. DNA polymerase I and III are responsible for elongating the DNA strand and replacing the RNA primer with DNA. The holoenzyme is a complex of different proteins involved in DNA replication, while DNA gyrase is responsible for relieving supercoiling in the DNA molecule.
