_____ moves outward from the origin of replication and breaks hydrogen bonds between DNA nucleotides.
A)RNA primase
B)Helicase
C)Topoisomerase II
D)DNA polymerase

Question

Quizplus · Accepted Answer

Helicase moves outward from the origin of replication and breaks hydrogen bonds between DNA nucleotides, allowing the DNA strands to separate and creating a replication fork. RNA primase is responsible for adding RNA primers to the template strand, Topoisomerase II relieves tension in the DNA double helix, and DNA polymerase adds nucleotides to the growing daughter strands.
