The enzyme that unzips the DNA to prepare for replication

• helicase

• replicase

• polymerase

• synthase

The process of DNA replication is called semi conservative because it results in

• none of these

• Two DNA molecules.  One original molecule and one with two new strands

• two exact copies with new strands

• two identical molecules, each with 1 original strand and one new.

The 5' end of DNA is marked by a(n)

• Phosphate Group

• Hydroxyl Group

• Purine

• Pyrimidine
