November 7 th , 2016 Professor Kaiming Ye BME 201 HW #10 1. Assuming the cell is perfectly spherical, with a radius of 5mm, it has a volume of 5.23 x 10^-13 L. The cell has a molecule concentration of 10 pM, which is equivalent to 1x10^-11 M. (1x10^-11 moles) x (5.23 x 10^-13 L) = 5.23 x 10^-24 (6.02 x 10^23 molecules / 1 mole) x (5.23 x 10^-24 m^3 / 1 cell) = 3.15 molecules. 2. Scenario 1: If the replication rate, μ and differentiation rate, δ are equal, then μ = δ. If these are expressed as the value q, the expression formed is: μ = δ = q Using this expression, Xout becomes: Xout = Xin * е^ (q/q) = Xin * е¹ Scenario 1: Xout = е * Xin Based on this, when μ = δ, Xout is the value of Xin times the constant e. Scenario 2: If δ is ten times slower than μ, then μ = (δ/10). Expressed in terms of q, with μ set to equal q, the expressions for μ and δ becomes: μ = q and δ = q/10

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
