Step by step
Solved in 2 steps
- What are the major cytoskeletal players involved in embryonic wound healing?a) Are actin filaments subject to the same "dynamic instability" as microtubules? Yes or no? b)Explain how both actin and microtubules polymerize and depolymerize.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.
- The Golgi complex functions to A) modify and secrete proteins to the external environment. B) sort proteins used within the cell. C) both modify and sort proteins into those destined for secretion and those that function in membrane structures. D) synthesize proteins.Kinetochores are the a) sites of spindle fiber attachment to chromosomes. b) regions where two chromosomes remain attached during mitosis. c) same as centromeres. d) structures that give support to the nuclear membrane12) Match the cell-cell junction on the left with the appropriate function on the right. Note that more than one letter may apply for a particular function and that each letter may be used more than once or not at all. A) Gap junctions provides a very strong attachment point between cells B) Desmosomes allow easy movement of large amounts of substances between adjacent cells C) Plasmodesmata seals the plasma membranes of adjacent cells together, preventing the movement of molecules between them D) Tight junctions
- Which term among A-D is not correctly matched with its definition? A) O Slime layer: loose assemblage of polysaccharide material external to the cell envelope B) O Polysome or polyribosome formation: multiple ribosomes binding to a messenger RNA transcript C) O Replisome: two of these complexes working in opposite directions are needed to copy the bacterial chromosome D) O Nucleoid: cytoplasmic area containing the bacterial chromosome E) OA-D are all correctly matchedFor each protein below, briefly explain whether it would or would not be required for the fusion of pre-peroxisomal vesicles to form a mature peroxisome: a) a SNARE protein, b) Dynamin c) A COPII adaptor proteinList 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…
