You've got to enter that prophase, baby
Before I stop lovin' you
Then enter __________-phase baby
And every word that I say is true
Your chromosomes are linin’
Up at the _________________
You've got ______________________ at the poles
You’ll be in anaphase later.
This can't go on
Lord knows you've got to divide
Baby, baby
