Select from the diagrams shown below to answer the following questions. If more than one answer is correct for a given question, provide only a single response. Which image shows correct bi-orientation? Which arrangement would have Aurora-B kinase phosphorylation of Ndc80? Which image has unstable attachment of kinetochores to spindle microtubules? Which arrangement would have a weak association between Ndc80 and kinetochore microtubules?

Choose ALL that can be a medium for marketing communication. 

Choose ALL statement(s) that is/are TRUE about social media campaign effectiveness.

For each of the microtubule proteins given, indicate whether association of this protein with microtubules would promote microtubule polymerization, microtubule depolymerization, or have no impact on the microtubule filament formation. Kinesin-13, a microtubule catastrophe factor [microtubule1] Augmin, a microtubule nucleating protein [microtubule2] Tau, a microtubule crosslinker [microtubule3] Katanin, a microtubule severing protein [microtubule4]

There are three major checkpoints in the eukaryotic cell cycle.  Identify two of the three checkpoints by name and indicate what is being monitored at each checkpoint. 

Questions 19-30 are derived from material covered in Chapter 17 of your textbook (Cell Cycle)

Prokaryotic cells have homologs of cytoskeletal proteins that are involved in all of the following activities except

Identify one method that can be used to determine whether cells in a population have gone through S-phase. List what cellular feature is being monitored in this method. Give a brief over view of how this method works.

Describe the specific enzymatic activity carried out by the Anaphase Promoting Complex (APC). Structure your response in a manner similar to the example given below. Example response: Hog1p is a protein kinase. As a protein kinase, Hog1p transfers the terminal phosphate from ATP onto target proteins such as Slt2p. When phosphorylated, Slt2p is activated.  

Augmin functions as a nucleating factor for microtubules. Which protein performs an analogous function for actin?
