Solution
The three key enzymes required for DNA synthesis are DNA polymerases, helicases, and ligases.
-
DNA Polymerases: These enzymes are responsible for synthesizing the DNA molecule. They add nucleotides to the growing DNA chain and are essential for DNA replication.
-
Helicases: These enzymes are responsible for unwinding the DNA double helix. They separate the two strands of DNA, allowing each strand to serve as a template for the synthesis of a new DNA molecule.
-
Ligases: These enzymes are responsible for joining the Okazaki fragments (short sequences of DNA nucleotides) together to create one continuous DNA strand. They play a crucial role in the replication of the lagging strand during DNA replication.
