Question

Quizplus · Accepted Answer

During DNA replication, each chromosome is copied to form two identical copies called sister chromatids. These chromatids contain one original DNA strand and one newly synthesized DNA strand. The original chromosome is not destroyed in the process. Therefore, option D is the correct answer. Options A, B, C, and E are incorrect as they do not accurately describe the process of DNA replication.
