Question

Quizplus · Accepted Answer

During DNA replication, each newly formed DNA molecule contains two new strands and two old strands. This is because the parental strands serve as templates for the synthesis of new strands, and the new nucleotides are added to the 3' end of the growing strand. As a result, each newly formed DNA molecule contains one parental strand and one newly synthesized strand in each of the two strands that make up the double helix.
