Questions & Step-by-Step Solutions
What is the function of the enzyme ligase in DNA repair?
Step 1: Understand that DNA can get damaged due to various reasons like UV light or chemicals.
Step 2: Know that when DNA is damaged, the cell needs to fix it to keep functioning properly.
Step 3: Recognize that during the repair process, the DNA is often cut into smaller pieces.
Step 4: Learn that ligase is an enzyme that helps to connect these smaller pieces of DNA back together.
Step 5: Conclude that the main function of ligase in DNA repair is to join the DNA fragments, ensuring the DNA strand is complete and functional again.
