Which IS true of cadherins?
A. They form tight junction
B. They are not tissue-specific
C. They are associated with a band of actin filaments
D. The bind TCF and prevent it from going into the nucleus
Homework Answers
The correct option C.
They are assosiated with a band of actin filaments.
Explanation:- the cell-cell adherens junction is a site for cadherin mediated cell adhesion where a band of actin filaments are densly assosiated with the plasma membrane.

Compared to the normal situation, in which actin monomers carry ATP, what do you predict would happen if actin monomers that bind a nonhydrolyzable form of ATP were incorporated into actin filaments? (a) Actin filaments would grow longer. (b) Actin filaments would grow shorter because depolymerization would be enhanced. (c) Actin filaments would grow shorter because new monomers could not be added to the filaments. (d) No change, as addition of monomers binding...

5. (5 points) Activation of Cdc42, a monomeric GTPase, triggers actin polymerization and bundling to form either filopodia or shorter cell protrusions called microspikes. These effects of Cdc42 could be mediated by N-WASp, which is a multifunctional protein. As shown in panel A, N-WASp contains a plectrin homology (PH) domain, which binds to PIP2 (phosphatidylinositol bisphosphate, PI(4,5)P2); a Cdc42 GTPase-binding domain (G); a verprolin homology domain (V), which binds to actin; a cofilin homology domain (C), which can bind to...

Question 78 Which of the following statements about the cytoskeleton is TRUE? All eukaryotic cells have actin, microtubules, and intermediate filaments in their cytoplasm The cytoskeleton provides a rigid and unchangeable structure important for the shape of the cell. The three cytoskeletal filaments perform distinct tasks in the cell and act completely independently of one another Actin filaments and microtubules have an inherent polarity, with a plus end that grows more quickly than the minus end С.
