Question

question 3
which statement best describes the dna molecules made from this process?
the new dna molecules are not identical to the original, providing variation in the dna.
the new dna molecules are each identical to only one strand in the original molecule.
the new dna molecules are identical to each other but not to the original molecule.
the new dna molecules are identical to each other and to the original molecule.

Explanation:

The image depicts the process of DNA replication. In DNA replication, the double - stranded DNA unwinds (step 2), and each strand serves as a template (step 3). Complementary base - pairing occurs (A with T and G with C). As a result, two new DNA molecules are formed (step 4). Each new DNA molecule has one original strand and one newly synthesized strand. Due to the rules of base - pairing (adenine pairs with thymine, guanine pairs with cytosine), the new DNA molecules have the same base sequence as the original DNA molecule. So, the new DNA molecules are identical to each other and to the original molecule.

Answer:

The new DNA molecules are identical to each other and to the original molecule.
