Question

Once RNA primers are removed, fragments of DNA that have been built separately must be joined together. What enzyme does this?
Helicase
Primase
DNA Polymerase III
DNA Polymerase I
Ligase

Answer 1

The enzyme that joins together the fragments of DNA after the RNA primers have been removed is **Ligase**. Specifically, DNA ligase is responsible for sealing the nicks between the Okazaki fragments on the lagging strand, creating a continuous DNA strand.
