Question

1. using your notes, book, and this assignment, place the steps of dna replication in the correct order.

____ a. the enzyme dna polymerase moves along the exposed strands and adds complementary nucleotides to each nucleotide in each existing strand.
____ b. the dna double helix breaks or unzips down the middle between the base pairs.
____ c. a complementary strand is created for each of the two strands of the original double helix.
____ d. two new identical dna molecules have been produced.

Explanation:

DNA replication begins with the unwinding of the double helix (step b). Then DNA polymerase adds complementary nucleotides (step a). This creates new complementary strands (step c). Finally, two identical DNA molecules are formed (step d).

Answer:

b, a, c, d
