The enzyme uses ATP to unwind the DNA template.

The enzyme uses ATP to unwind the DNA template.

Step 1: The enzyme recognizes the DNA template that needs to be unwound. Step 2: The enzyme binds to the DNA template at a specific site. Step 3: ATP (adenosine triphosphate) is a molecule that provides energy for cellular processes. The enzyme uses ATP as a source of energy. Step 4: The enzyme uses the energy from ATP to break the hydrogen bonds between the base pairs of the DNA template. Step 5: As the hydrogen bonds are broken, the DNA strands separate and unwind. Step 6: The enzyme continues to move along the DNA template, using ATP to unwind the remaining sections. Step 7: Once the DNA template is completely unwound, the enzyme can proceed with its specific function, such as DNA replication or transcription.
