- step 1: enzyme that unwinds the helix by breaking hydrogen bonds
- proofreading (nuclease) and repair (polymerase) help prevent _____________.
- step 3: proofreads the DNA during replication and repairs errors
- process by which DNA is copied in a cell before it divides
- which strand of DNA is made continuously and which is made piece-by-piece?
- Each new DNA molecule is made of one strand from the original DNA molecule and one new strand. This makes the replication of DNA ______________.
- step 3: enzyme fills in gaps especially in lagging strand
- step 2: form new strands at the replication forks by adding complementary nucleotides to each of the original strands
