Answer:
The correct option is <em>A. Two molecules are formed, each with one original side</em>
Explanation:
When a DNA is duplicated, initially the bonds between the complementary DNA strands are broken. Each strand serves as a template to generate a new strand. Nitrogenous bases are added complementary to both the templates and two new strands are generated. In this way, two new strands are formed with each being complementary to one of the original strands. This method is known as the semi-conservative method of DNA replication.
