Twas the night before Christmas and all through the cell,
Not a creature was stirring, not even an organelle.
The chromosomes were hung in nucleus with care,
In hopes that mitosis would soon take place there.
The genes were all nestled and snug in their beds,
While cells in their pj’s and vacuoles of sap,
Had just settled down for their Interphase nap.
Then in the nucleus there arose such a clatter,
The chromosomes sprang from their beds to see what was the matter.
They flew from the nucleoplasm in less than a flash,
Hit the nucleolus and made quite a crash.
