According to the semi-conservative model of DNA replication, two DNA molecules result:
Correct answer: A. Each strand with one new strand and one original strand
- A. Each strand with one new strand and one original strand
- B. Each with two new strands
- C. One with two new strands and one with both original strands
- D. Each with two original strands
Explanation
This is correct. In the semi-conservative model, during DNA replication, each original DNA strand serves as a template for the synthesis of a new complementary strand. Therefore, in the resulting two DNA molecules, each one consists of one original strand and one newly synthesized strand.
