Do DNA replication processes occur the same way on leading and lagging strands?

Do DNA replication processes occur the same way on leading and lagging strands?

• A. True
• B. False
• C. Only during the initial phase
• D. Only in prokaryotic cells

Answer: (B)

DNA replication processes do not occur the same way on leading and lagging strands, which is why the correct answer is false. During DNA replication, the leading strand is synthesized continuously in the direction of the replication fork movement, allowing for a smooth addition of nucleotides. In contrast, the lagging strand is synthesized discontinuously in short segments known as Okazaki fragments, which are formed in the opposite direction of the replication fork movement. This necessitates the repeated initiation of synthesis, as each Okazaki fragment is created separately and later joined together. Hence, the mechanisms and processes for synthesizing these two strands differ significantly, validating that the two processes are not the same.
