The correct Answer is:
To solve the question regarding the number of new strands formed during DNA replication, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding DNA Structure**: - DNA is a double-stranded molecule composed of two complementary strands that are held together by hydrogen bonds. 2. **Identifying Parental Strands**: - During replication, the two original strands of DNA serve as parental strands. These strands will act as templates for the synthesis of new strands. 3. **Separation of Strands**: - The two parental strands separate during the replication process. This separation allows each strand to serve as a template for the formation of new strands. 4. **Synthesis of New Strands**: - As the parental strands separate, new complementary strands are synthesized. Each parental strand will produce one new strand, resulting in two new strands being formed. 5. **Conclusion**: - Therefore, when a DNA molecule undergoes replication, the total number of new strands formed is **2**. ### Final Answer: When a DNA molecule undergoes replication, the number of new strands formed is **2**. ---
