What happens to the two strands of a dna molecule after replication? a. both strands change the order of their bases and pair back again to form a different dna molecule. b.each strand forms a new dna molecule by pairing up with a complementary new strand. c.each strand forms a single-strand dna molecule. d.each strand splits in two and forms a new double-strand dna molecule.

The initiation of DNA replication occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on theDNA strands, thereby pulling apart the two strands.

"In both cases, replication occurs so quickly because multiple polymerases can synthesize two new strands at the same time by using each unwoundstrand from the original DNA double helix as a template. One of these original strands is called the leadingstrand, whereas the other is called the lagging strand."
