Final answer:
In meiosis, M-Cdk activity remains inactive during metaphase arrest.
Step-by-step explanation:
In meiosis, M-Cdk activity remains inactive during metaphase arrest.
M-Cdk, or Maturation Promoting Factor, is a key regulator of the cell cycle and plays a crucial role in controlling the progression of cells through various phases. During metaphase arrest, M-Cdk activity is kept low to prevent premature separation of sister chromatids. This allows for proper alignment and attachment of chromosomes to the spindle fibers before the onset of anaphase.
