What enzymes must be present for DNA replication to proceed normally?
A)DNA polymerase and RNA polymerase
B)mRNA,rRNA,and tRNA
C)RNA helicase,DNA helicase and DNA polymerase
D)DNA topoisomerase,RNA polymerase,and RNA ligase
E)DNA polymerase,DNA ligase,and DNA helicase

Question

Quizplus · Accepted Answer

DNA replication requires the unwinding of the double helix, which is accomplished by DNA helicase. DNA polymerase is responsible for the addition of new nucleotides to the growing DNA strand, and DNA ligase is responsible for joining the Okazaki fragments on the lagging strand. Therefore, the enzymes required for DNA replication to proceed normally are DNA polymerase, DNA ligase, and DNA helicase.
