Question

Quizplus · Accepted Answer

In semiconservative DNA replication, each new double helix formed will have one new and one old strand in each helix. This is because during replication, the original two strands of DNA separate and each one serves as a template for the synthesis of a new, complementary strand. As a result, each new double helix will contain one original (old) strand and one newly synthesized (new) strand.
