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.

About Structure of DNA
DNA structure includes nucleotides made of deoxyribose, phosphate and nitrogenous bases, arranged in two antiparallel polynucleotide strands. Questions cover the double helix, phosphodiester and hydrogen bonds, complementary base pairing between adenine and thymine and between guanine and cytosine, and the significance of major and minor grooves.
