WebbAll steps. Final answer. Step 1/2. 1. Helicase: Helicase is an enzyme that unwinds the double-stranded DNA molecule by breaking the hydrogen bonds between the two strands. This creates a replication fork where the DNA strands are separated and exposed for further processing. View the full answer. Step 2/2. WebbOne of the key molecules in DNA replication is the enzyme DNA polymerase. DNA polymerases are responsible for synthesizing DNA: they add nucleotides one by one to the growing DNA chain, incorporating only those that are complementary to the template. …
WebbProofreading by DNA polymerase corrects errors during replication. Some errors are not corrected during replication, but are instead corrected after replication is completed; this type of repair is known as mismatch repair …
