Problem
A transcription factor is present at a concentration of 2nM in a bacterial cell of volume 2fL. Treat the copy number of this molecule in a single cell as a Poisson random variable with mean nˉ=cNAV.
((a)) Find the mean copy number nˉ.
((b)) Find the percentage of cells that contain zero copies, exactly one copy, and two or more copies.
