Question

Quizplus · Accepted Answer

Continuous cell lines can be maintained through an indefinite number of generations, which is the main difference between them and primary cell lines. Primary cell lines have a limited lifespan and can only be cultured for a finite period of time before they stop dividing and eventually die. Continuous cell lines, on the other hand, have acquired mutations or alterations that allow them to continue dividing indefinitely in culture.
