A cell analogy for chromatin could be something like a library. This is because it serves at a single hub for human genes' genetic information.
In an analogy comparing the cell to a school, the chromatin could be the Assistant Principal/s because they carry the information the principal ordered.
a library because it stores all the information
a city border!!
The cell city analogy for a nucleus would be a city hall. This is because a city hall is the thing that controls the whole cell.
A cell city analogy for micro-filaments would be scaffolding, or anything that supports a structure.
the blueprints of the city
that is not correct
It a eukaryotic cell were a city, the chromatin would make up the telephone lines. Chromatin transmits the DNA to the cell just as phone lines transmit calls to one's phone.
