Steps of DNA Replication
Multiple Choice
Multiple ChoiceWhich one of the following statements regarding DNA replication is correct?
A
Ligase assembles nucleotides into Okazaki fragments. Then polymerase joins these fragments together into a DNA strand.
B
The two strands of DNA separate, and nuclease enzymes digest one strand. Then DNA polymerase synthesizes two new strands out of the old ones.
C
The two strands separate, and each one receives a complementary strand of RNA. Then this RNA serves as a template for the assembly of many new strands of DNA.
D
Ligase separates the two strands of the DNA double helix. Then DNA polymerase synthesizes the leading strand and primase synthesizes the lagging strand.
E
Helicases separate the two strands of the double helix, and DNA polymerases then construct two new strands using each of the original strands as templates.
