Quizplus · Accepted Answer

Temperature-sensitive mutations were essential to the discovery of new replication enzymes because they enable researchers to manipulate the function of the enzyme at different temperatures. This allowed for the identification of mutations that affect enzyme activity and enabled the discovery of new replication enzymes. Gain-of-function mutations could also potentially aid in this discovery, but they were not specifically mentioned in relation to replication enzymes. Lethal mutations are unlikely to be useful in discovering new enzymes because they cause the death of the organism.
