Method |
Model of tightly packed viral DNA. Equation (3) on page 118 Force bend=(k*epsilonP)/(2*R^2) where k=flexural rigidity,epsilonP=persistence length,R=radius of bent DNA. Taking R of lambda phage, 29nm |
Comments |
pN=picoNewton=10^-12Newton. This is the force required for initial stage of packaging. It increases as more DNA is wound around 'inversed spool'. This is a relatively small force compared to the maximum forces exerted by molecular motors, which are typically in the pN regime. |
