At … WebA) Unwinding of the DNA molecule occurs as hydrogen bonds break. B) Replication occurs as each base is paired with another exactly like it. C) The process is known as semiconservative replication because one old strand is conserved in the new molecule. D) The enzyme that catalyzes DNA replication is DNA polymerase.
