List and describe the three main types of cytoskeleton. If you wanted to do immunocytochemistry to specifically stain each type of cytoskeleton, what is a protein that could be used for each cytoskeletal type (in other words, what is a unique protein for each cytoskeletal type)?
What are three types of actin structures? Describe the involvement of actin structures in cell migration.
How is the growth and shrinking of microtubules regulated? Then describe the roles of microtubules in: chromosomal separation during mitosis and the movement of organelles and vesicles within a cell.
Describe a possible mechanism on how signaling pathways might impact the cytoskeleton, so that cell migration could be regulated in a localized manner within a multicellular organism. (hint: think about the possible transcriptional regulation of the G-protein regulators)
What are 2 main challenges of protein targeting? Then describe one way these challenges are overcome during signal-based targeting and one way…
The nucleus
a) has a single membrane and compartmentalizes the genetic material
b) has a double membrane joined by nuclear pores, is continuous with the endoplasmic reticulum membrane, and compartmentalizes the nuclear genetic material
c) has a double membrane joined by nuclear pores, is continuous with the smooth endoplasmic reticulum membrane only, and compartmentalizes the nuclear genetic material
d) None of these are accurate
Which of the following is found in binary fission but not in mitosis?
a) duplicated chromosomes attach to the plasma membrane
b) replicated strands of DNA seperate
c) the result produces 2 nuclei
d) following the process, a membrane seperates the 2 copies
e) replication of DNA begins at an origin

- The nucleus is the largest of the eukaryotic organelles and contains the genome of the organism. a) describe the proteins and process of nuclear import and export. b) describe, in general terms, an experiment that could be conducted to show that there are specific signals for nuclear import or export.arrow_forwardSuppose cells in an experiment had been labeled with green fluorescent tubulin. At the onset of Anaphase B, you use your laser to bleach a stripe across all of the microtubules on one side of the spindle as shown by the dashed line. This does not hurt the function of the microtubules in any way, but the bleached, nonfluorescent subunits in the microtubules now serve to mark a fixed location relative to the (+) and (-) ends. pl. membr. spindle A. Label one of each of the following: kinetochore MT, astral MT, polar MT. Indicate (+) and (-) ends. B. As the cell progresses through anaphase B, do the bleached spots get closer to, further from, or stay the same distance from the spindle pole they are embedded in? Why? Do they get closer to, further from, or stay the same distance from the plasma membrane? Why?arrow_forward50. Cell motility involves the coordination of many events in the cell. In cells lacking flagella/cilia, which of the following are NOT required for cell motility? a) extension of actin filaments b) transmembrane proteins associating with extracellular matrix proteins in the underlying surface c) myosin-mediated contraction at the rear of the moving cell d) formation of a microtubule array in the leading edge of the cell e) formation of plasma membrane extensions such as pseudopodia or filopodiaarrow_forward
