What is the role of enzymes in the DNA replication process?
Group of answer choices
Enzymes split the DNA molecule into two strands and then transport corresponding nitrogenous bases to each strand.
Enzymes link together to form a template for a new DNA molecule to be built.
Enzymes read the DNA code and build a new DNA molecule from scratch.
Enzymes link adjacent nucleotides together, becoming an integral part of the structure of the new strands of DNA.

Correct answer: "Enzymes read the DNA code and build a new DNA molecule from scratch."
Explanation: During replication enzymes carry out the work—helicase unwinds and separates the strands, primase makes short RNA primers, and DNA polymerase reads each template strand and adds complementary nucleotides to synthesize the new strand (ligase later joins fragments). Note: DNA polymerase needs an RNA primer to start, so synthesis isn’t begun entirely without a primer. Other choices are inaccurate (enzymes don’t “transport” bases, don’t become part of the DNA, and don’t themselves form the template).
