What is the general outcome in terms of DNA molecules after replication?

• A. One Copy Remains Original While the Other Is Damaged
• B. Two Identical Copies Are Formed From One Original Molecule
• C. The Original Molecule Is Duplicated and Modified
• D. The Original Molecule Is Unchanged

Answer: (B)

DNA replication makes two daughter DNA molecules that are genetically identical to the original. This happens through a semi-conservative process: the double helix unwinds, and each old strand serves as a template for a new complementary strand. Because base pairing is precise, the new strands replicate the sequence accurately, so the two new molecules end up with the same genetic information as the original and as each other (aside from occasional replication errors). That’s why the general outcome is two identical copies formed from one original molecule. The other descriptions describe scenarios (damage, modification, or no change) that don’t reflect normal replication.
