Molecular basis of heredity · Zoology

The enzyme helicase functions to:

  1. Join adjacent Okazaki DNA fragments
  2. Unwind the DNA double helix
  3. Add RNA primers to the template
  4. Correct replication errors
Show answer and explanation

Correct answer: Unwind the DNA double helix

Helicase unwinds the DNA helix by breaking hydrogen bonds. This allows replication to proceed.
