Which of the following enzymes below plays a role in joining the short fragments in the growing DNA strand a. Helicase b. topoisomerase c. primase d. ligase

The correct answer is d. ligase.<br /><br />Ligase is an enzyme that plays a crucial role in joining the short fragments in the growing DNA strand during DNA replication. It catalyzes the formation of phosphodiester bonds between the fragments, effectively linking them together to form a continuous DNA strand.
