How does myoblast and myotube differs in cytoskeletal components of their microfilaments (actin), microtubules (tubulin), and Intermediate filaments (Vimentin).
Homework Answers
Myoblast embryonic, progeniter cells fuses to form primary myofibres then differentiated to form secondary myofibres then migration adn adhesion of cells takes place which leads to formation of myocytes and nascent myotube differentiated into mature myotube.

Intermediate filaments are an essential class of cytoskeletal proteins. Give three examples of how they different from the other cytoskeletal systems, i.e., microtubules and microfilaments. (The best answer will include some details about the other cytoskeletal elements, e.g., composition, proteins that bind actin/tubulin, etc.)

EpothiloneB: binds to b-tubulin and prevents depolymerization Many chemotherapeutic drugs target microtubules and microfilaments. Two drugs are listed below. One affects microtubules and one affects microfilaments. These drugs ACT ON THE NORMAL PROCESSES of cytoskeletal dynamics. Use your understanding of these processes to postulate on how the drug achieves its effect! Given the effect of the drug what stage or stages of the cell cycle might be affected by this drug? Explain your reasoning

1) What is nucleation? How are microtubules nucleated? How is Actin commonly nucleated? 2) How do motor proteins work? Why is it important that these proteins have two domains that interact with the cytoskeletal element (“feet”)? 3) Give two examples of Actin binding proteins that would affect actin dynamics. 4) Intermediate filaments are very different from the other two cytoskeletal elements. What are those differences?
