Answer 1

Answer: C). Two copies of a DNA molecule

Explanation: Replication is a biochemical process in which a DNA molecule is copied into to produce another DNA molecule that is complementary to the parent DNA. During replication, a double helical DNA molecule is unwind by the enzyme helicase which separates the two strands of DNA. DNA polymerase then catalyzes the production of a complementary strand using the two unwind parent strands as templates. The result of this is the production of two double stranded DNA that are identical to the parent DNA molecule. Each of the two double stranded DNA formed contains one strand of the parent DNA and one strand of the newly synthesized DNA strand.
