Mitotic CDKs affect nuclear envelope components by specific mechanism. Which of the following statement is not related to this mechanism?

#SCPH06 I Botany
  1. The CDKs phosphorylate specific nucleoporins, which causes nuclear pore complexes to dissociate into subcomplexes during prophase. 
  2. Phosphorylation of integral membrane proteins of the inner nuclear membrane causes depolymerization of the lamin intermediate filaments.
  3. The weakening of the associations between the inner nuclear membrane proteins and the nuclear lamina and chromatin allows sheets of inner nuclear membrane to retract into the endoplasmic reticulum, which is continuous with the outer nuclear membrane.
  4. Mitotic CDKs induce the formation of the mitotic spindle. The function of the mitotic spindle is to segregate chromosomes so that the sister chromatids separate from each other and are moved to opposite poles of the cell.

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.
