The enzyme responsible for catalyzing the formation of two new DNA strands during DNA replication is DNA polymerase.

Here's how it works:

* DNA polymerase reads the existing DNA strand as a template and adds complementary nucleotides to form a new strand.

* There are multiple types of DNA polymerase, each with specific roles in the process. For example, DNA polymerase III is the primary enzyme responsible for DNA synthesis in bacteria.

* DNA polymerase is essential for maintaining genetic information and ensuring that the correct sequence of nucleotides is copied accurately.
