Precision will be reduced, but yield will be increased

Optimisation of a PCR reaction is often a compromise between the competing demands for precision, efficiency and yield. Although the specific effects may vary, generally, increasing the annealing temperature will increase non-specific primer binding and reduce precision. Increasing the length of the elongation phase will reduce the proportion of incomplete newly-synthesised strands and therefore increase yield. In this case, the potential effect on efficiency is unclear. Increasing the elongation phase would increase the reaction time, but the time taken to ramp down to a lower annealing temperature would be reduced.

Which of the following true about real time PCR?

the centrifugal separation of biomass of 80um sized cells of density 1.04kgm^-3 was carried out in a tubular centrifuge having a diameter of 15cm and rotating at 1200 rev/min. the axis of rotation was 0.8cm, the liquid viscosity were 1.0kgm^-3 and 0.013 gcm-ls^-1 respectively. Calculate the volumetric capacity of the centrifuge if its length was 40cm?
