Thus, there may be an evolutionarily conserved asymmetry in the metaphase checkpoint, which may reveal something about its mechanism.
Checkpoint proteins are crucial for cellular responses to injury, including radiation damage.
Obviously, a processor can always transmute into a checkpoint by just standing still.
We conclude, therefore, that the replication-sensitive checkpoints that operate during mitosis are absent or inactive during meiosis.
An extension of this examined the possibility of checkpoints during meiosis itself, specifically during metaphase.
We cannot exclude the possibility that the spindle assembly checkpoint acts during the first mitosis.
Meiotic spindle and spindle checkpoint proteins are responsible for normal chromosome alignment and separation during meiosis.
In this study, we addressed the developmental activation of the metaphase checkpoint in the zebrafish embryo.
