Okazaki fragments are short DNA segments synthesized on the lagging strand during replication. DNA ligase plays a critical role by sealing nicks between these fragments to form a continuous DNA strand. Other enzymes like helicase and primase have distinct roles, such as unwinding DNA and synthesizing primers, respectively
