Questions & Step-by-Step Solutions

What is the function of DNA ligase during replication?
  • Step 1: Understand that DNA is made up of two strands that need to be copied during replication.
  • Step 2: Know that the two strands are called the leading strand and the lagging strand.
  • Step 3: Realize that the lagging strand is made in small pieces called Okazaki fragments.
  • Step 4: Learn that DNA ligase is an enzyme that helps join these Okazaki fragments together.
  • Step 5: Understand that by joining the fragments, DNA ligase creates one continuous strand of DNA on the lagging side.
