Solution
The enzyme that joins DNA fragments together, such as Okazaki fragments, is DNA ligase. Here are the steps:
-
During DNA replication, the enzyme DNA polymerase synthesizes new strands of DNA. However, on the lagging strand, it does this in segments known as Okazaki fragments.
-
These fragments are separate pieces of DNA and need to be joined together to form a continuous strand.
-
This is where DNA ligase comes in. DNA ligase is an enzyme that facilitates the joining of DNA strands together by forming a bond between the phosphate group of one strand and the deoxyribose group on another.
-
DNA ligase moves along the lagging strand, sealing the gaps between the Okazaki fragments, thus creating a continuous DNA strand.
So, the answer to your question is DNA ligase.
