When a DNA molecule unzips and enzymes work to form two identical DNA molecules, this is the process called a) replication
b) variation
c) amplification
d)
specialization

A) is your answer!

DNA replication occurs through the help of several enzymes. These enzymes "unzip" DNA molecules by breaking the hydrogen bonds that hold the two strands together. Each strand then serves as a template for a new complementary strand to be created.
