Question: What role does DNA ligase play in recombinant DNA technology?

Options:

Correct Answer: It joins DNA fragments together

Solution:

DNA ligase is an enzyme that joins DNA fragments together, which is crucial for creating recombinant DNA.

What role does DNA ligase play in recombinant DNA technology?

What role does DNA ligase play in recombinant DNA technology?

Step 1: Understand that DNA is made up of smaller pieces called fragments.
Step 2: Know that recombinant DNA technology involves combining DNA from different sources.
Step 3: Realize that when scientists want to join these DNA fragments, they need a special helper.
Step 4: Learn that DNA ligase is the enzyme that helps to join these DNA fragments together.
Step 5: Remember that without DNA ligase, the DNA fragments would not stick together, making it impossible to create recombinant DNA.
