T4 is a large spherical virus with an approximately spherical head group which contains DNA. These head particles have the following characteristics:
s0 20,w = 1025 S D0 20,w = 3.6 x 10^(-8) cm2/s V2 = 0.605 cm^3/g (this is the partial specific volume)
Calculate: a) The molecular weight of the head group
b) The volume of the head group from the partial specific volume (assume no hydration)
c) The frictional coefficient of the head group from the diffusion coefficient
d) The volume of the head group from the frictional coefficient in part c and Stokes equation.
e) How many g of water of hydration are there, per g of protein?
