Answer:
During DNA replication, the leading and lagging strands are synthesized differently due to the antiparallel nature of the DNA double helix.
Step-by-step explanation:
The leading strand is synthesized continuously, while the lagging strand is synthesized discontinuously in small fragments called Okazaki fragments. This process occurs during the elongation stage of DNA replication.
The leading strand is built continuously in the same direction as the replication fork, while the lagging strand is synthesized discontinuously in the opposite direction in the form of Okazaki fragments. This mechanism ensures efficient and accurate replication of both DNA strands during the elongation phase of DNA replication.
