What is the role of helicase in DNA replication? (2022)
Steps
Concepts
Step 1: DNA is made up of two strands that are twisted together, forming a double helix.
Step 2: Before DNA can be copied, these two strands need to be separated.
Step 3: Helicase is an enzyme that helps to unwind and separate the two strands of the DNA double helix.
Step 4: Once the strands are separated, other enzymes can come in to copy each strand to make new DNA.
