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

Question

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.
