DNA Replication - Living Environment H: 8(A,C)
... DNA Replication • The two strands of DNA unwind or “unzip” breaking the hydrogen bonds and separating. Then each strand becomes the guide or “template” for the making of a new strand. • A protein called an enzyme called DNA polymerase breaks the nitrogen base bonds and the two strands of DNA separa ...
