Final answer:
Okazaki fragments are short DNA segments synthesized on the lagging strand away from the replication fork and are not found on the continuous leading strand.
Step-by-step explanation:
Okazaki fragments are not formed on the leading strand during DNA replication. Okazaki fragments are short stretches of DNA synthesized on the lagging strand in the direction away from the replication fork. During replication, DNA polymerase can only add nucleotides in the 5′ to 3′ direction. Therefore, as the fork progresses, one strand, the leading strand, is synthesized continuously towards the replication fork. The other strand, known as the lagging strand, must be synthesized in a discontinuous manner. This process involves the synthesis of Okazaki fragments, which are later connected by the enzyme DNA ligase after the RNA primers are replaced with DNA.
