In a migrating neutrophil, the GTPases Rac and Rho are active in different areas of the cell, and each antagonizes the other. What would happen if Rac STOPPED antagonizing Rho?

TRUE or FALSE: During necrosis, the cell disassembles its cytoskeleton, nuclear envelope and DNA in a self-contained manner. It frequently does this in response to developmental signals. 

The leading edge of a cell (the area of a migrating cell that is closest to the direction of movement) is pictured in the diagram below, with two structures within it labeled as A) and B). What are each of those structures called?  

Name the E3 ligase that ubiquitinates M-cyclins, tagging them for destruction in a proteasome.

Based on the higher order structure of actin microfilaments characterizing different areas of an interphase cell, which area would you expect to contain a high concentration of Arp2/3 proteins present?

Piloting and revising the questionnaire or interview schedule is a step that must be included when building a new measure.

A junction that connects adjacent cells directly to one another through catenin proteins and depends on high Calcium ion concentration to form is called:

Which cell’s mitochondria do you expect to contain more cristae?

Qualitative research is performed to enable discovery when there is insufficient prior understanding of a topic, or when preconceived concepts and predefined tools have inadequately captured the phenomena of interest.

TRUE or FALSE: The stability of an actin microfilament depends on the presence of a “GTP cap”
