WebAll 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.

Some errors are not corrected during replication, but are instead corrected after replication is … WebJul 25, 2024 · During replication, the DNA polymerase proofreads newly added nucleotides before adding the next one. If it finds an error, it stops the process, cuts out the mismatched base pairs, and adds the correct nucleotide before moving forward. This specific function of DNA polymerase ensures the integrity of the genetic information is maintained.
