Question:
The action of helicase creates _____.
1. Primers and DNA fragments
2. DNA fragments and replication forks
3. DNA fragments and replication bubbles
4. Primers and replication bubbles
5. Replication forks and replication bubbles
Answer:
The action of helicase creates DNA fragments and replication forks.
Explanation:
Helicase is an enzyme that unwinds the double helix structure of DNA by breaking the hydrogen bonds between the base pairs. This process creates two single strands of DNA that serve as templates for synthesizing new complementary strands.
The unwinding of the DNA double helix creates two replication forks, the sites where DNA replication occurs. As the helicase continues to move along the DNA strands, it creates DNA fragments that are eventually joined together by other enzymes, such as DNA ligase, to form a completely replicated DNA molecule.
