Which factor does not help to explain why many proteins exhibit quaternary structure?

#Part-B Specialized Branches in Biotechnology
  1. Oligomers are usually more stable than the free monomers.

  2. Active sites can be formed when the protein chains associate.

  3. The subunits always are able to maintain the same three-dimensional structure whether they are associated into an oligomer or not.

  4. Increased efficiency by the sharing of the same subunit with the same function among different proteins.

The series of events by which APC/C promotes the separation of sister chromatids at anaphase.
A. all the kinetochores have attached to spindle microtubules and the spindle apparatus is properly assembled and oriented.
B. Cdc20 specificity factor associated with APC/C directs it to ubiquitinylate securin and mitotic cyclins. 
C. A protease known as separase cleaves the cohesin subunit Scc1 (Rad21), breaking the protein circles linking sister chromatids.
D. anaphase begins as poleward force exerted on the kinetochores moves the split sister chromatids toward opposite spindle poles.
E. Following securin degradation and a decrease in mitotic CDK activity.
Which of the following series is correct?
