Injection of an Immature Xenopus Oocyte with MPF Induces

Question

Injection of an immature Xenopus oocyte with MPF induces:
A)meiosis.
B)oocyte maturation.
C)synthesis of progesterone.
D)meiosis and oocyte maturation.

Accepted Answer

MPF or maturation promoting factor is a key regulator of meiosis and oocyte maturation in Xenopus oocytes. Injection of an immature oocyte with MPF triggers both meiosis and oocyte maturation. Therefore, option D is the correct answer. Synthesis of progesterone is not directly induced by MPF.
