What Are the Four Steps of DNA Replication?

The four steps of DNA replication are the unwinding of two coiled strands of DNA, complementary pairing of nucleotide bases, completion of the joins and continuous and discontinuous synthesis

Unwinding must occur in order for DNA replication. Two strands of DNA that are connected and wound into a double helix separate from each other. This separation creates a replication fork, and enzymes connect the existing exposed bases with complementary free nucleotide triphosphates. To complete the joins, an enzyme called polymerases starts the chemical reaction that allows for the joining of phosphate and deoxyribose sugar. The DNA chain can only continue to extend in one direction. Enzymes called ligases are used to create a continuous and complete DNA molecule.
