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
In some eukaryote organisms, myocytes are a type of stem cell that become Muscle cells. These cells filled with a protein called myosin. Such cell products are stored in cell structures that are formed from: A) the nucleus, B) from the smooth ER as vesicles, C) are engulfed into the cell by phagocytosis, D) are released from the cell by the process of Exocytosis, E) the lysosomes.
