Question

Quizplus · Accepted Answer

During DNA replication, both strands are shortened, but at opposite ends due to the nature of DNA polymerase only being able to add nucleotides in the 5' to 3' direction. This results in the leading strand being synthesized continuously, while the lagging strand is synthesized in short segments known as Okazaki fragments, leading to shortening at opposite ends.
