Quizplus · Accepted Answer

When MPF (mitosis-promoting factor) is introduced into immature frog oocytes that are arrested in G₂, the cells enter mitosis. MPF is a cyclin-dependent kinase that promotes the progression from G₂ phase to mitosis. Therefore, the introduction of MPF would overcome the G₂ block and trigger the entry of the cells into mitosis.
