The other one, the female pronucleus, takes shape from the nucleus of the ovum, and then the two then start to approach each other, pulled along a protein scaffolding, or mitotic spindle, between the two.

另一个，雌性原核，从卵子的胞核形，两者开始相互接近，在两者之间沿着蛋白质支架或有丝分裂纺体拉动。

It's in these three, G1, S and G2 and the actual copying of the nucleus and copying of the cell, this mitotic phase is actually going to be really, really small.

在G1、SG2这三个阶段，以及实际的胞核复胞复过程中，有丝分裂阶段其实会非常、非常短暂。

Cyclin A will actually build up during the S phase and then it'll drop off right as the cell divides, as it goes into this mitotic phase.

周期蛋白A实际上会在S期积累，在胞分裂时，也就是进入有丝分裂期时减少。

And so all of these together will work on pushing that cell into the mitotic phase or into this next step of the cell cycle.

而所有这些因素共同作用，会推动胞进入有丝分裂阶段或胞周期的下一步。
