Which enzyme is responsible for synthesizing new DNA strands?

Explanation:
DNA polymerase is the enzyme responsible for synthesizing new DNA strands during DNA replication. It catalyzes the addition of nucleotides to the growing DNA strand by reading the template strand and matching complementary nucleotides, thus forming a new double-stranded DNA molecule. This process is crucial for cell division, ensuring that genetic information is accurately copied and passed on to daughter cells. In addition to its role in synthesizing new strands, DNA polymerase also has a proofreading function, allowing it to correct mistakes during DNA replication, which helps maintain the integrity of the genetic code.
