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

#Unit 2. Cellular Organization
  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.

Dozens of potato varieties exist, differing from each other in potato-tuber size, skin color, flesh color, and shape. One might construct a classification of potatoes based on these morphological traits. Which of these criticisms of such a classification scheme is most likely to come from an adherent of the phylocode method of classification?
