Verified step by step guidance1
Understand the process of DNA replication, which involves the synthesis of new DNA strands from a template strand.
Recognize that DNA replication occurs in a direction-specific manner, with the enzyme DNA polymerase synthesizing new strands in the 5' to 3' direction.
Identify the leading strand as the strand that is synthesized continuously in the direction of the replication fork movement.
Identify the lagging strand as the strand that is synthesized in short fragments, known as Okazaki fragments, which are later joined together.
Conclude that the correct statement is: 'The leading strand is synthesized continuously, while the lagging strand is synthesized in fragments.'
