Homework Answers
Ans. Actin polymerization of monomers into polarised filaments aids cancer cells to crawl.
the actin cytoskeleton self-assembles at the cell front and acts to generate the forces.
actin filaments assembly against the membrane at the leading edge generates a tension, which propagates isotropically and evenly throughout the whole membrane, including the membrane at the rear edge. The latter faces the remnants of the actin network and, because of the tension, pushes on them.

of the three types of fibers; microfilaments (or and intermediate filaments are fibers with diameters in a Microtubules are the filaments) are the middle range. Microtubules are hollow rods about 25 nm in diameter and 200 nm to 25 um in length. Microtubule fibers are constructed of the globular protein A tubulin dimer consists of two slightly different polypeptides: a-tubulin and B-tubulin. Microtubules shape and support the cell and serve as tracks to guide motor proteins carrving organelles to their...

Question 1 20 pts Cytochalasin is a drug that caps actin filament plus ends, thus preventing actin polymerization. Phalloidin is a drug that binds to and stabilizes actin filaments, preventing actin depolymerization. Even though these drugs have opposite effects on actin polymerization, the addition of either of these drugs instantaneously freezes the cell movements that depends on actin filaments. Explain why drugs that have opposite effects on actin filaments can have a similar effect on cell movements.

Question 9 1 pts Why are inherited forms of cancer autosomal dominant but not fully penetrant? Even if the mutation is inherited, a loss-of-funciton mutation ipmscting one allele is not expressed The inherited allele is dominant at the cellular level, but might not be expressed depending on genetic background Most inherited mutations are recessive at the cellular level Sporadic, but not inherited forms of cancer forms of cancer are caused by somatic mutation Question 10 1 pts Select true statements...
