DNA Replication

Okazaki fragments are unified into a single continuous strand by the use of this enzyme

• DNA Helicase

• DNA Ligase

• Topoisomerase

• Telomerase

This enzyme is responsible for creating telomeres added to the ends of DNA

• Topoisomerase

• Telomerase

• DNA Helicase

• DNA Primase

A process in which DNA has the unique ability to make an exact copy of itself.

• Replication

• Translation
