- Addition of which of the following would increase the rate of actin depolymerization on the minus end of the filament by dissociating ADP-actin? Othymosin-b4 O cofilin O ATP-G-actin O profilin O Cap ZActin filaments have a defined polarity. What is filament polarity? How is it generated at the subunit level?Under certain stable concentration conditions, actin monomers in their ATP form will polymerize to form filaments that disperse again into free actin monomers over time. Explain
- Neurofilament proteins assemble into long, intermediate filaments , found in abundance running along the length of nerve cell axons. The C-terminal region of these proteins is an unstructured polypeptide, hundreds of amino acids long and heavily modified by the addition of phosphate groups. The term “polymer brush” has been applied to this part of the neurofilament. can you suggest why?Why is the proportion of actin within filaments in cells smaller than would be predicted by in vitro experiments?hich of the following statements is true about actin: OActin is translated by free ribosomes O Dyneins move toward the minus end of actin filaments actin can bind to GTP O actin filament is stabilized by ADP-binding
- What is meant by the term "Critical concentration" with respect to actin filaments?If the graph represents one actin filament, and line A represents dynamic activity at the plus end and line B represents dynamic activity at the minus end, which of the following must be true? Group of answer choices Formin proteins have been removed. Treadmilling is occurring at 1000 mM. CapZ proteins are not present. Nucleation is occurring at 100 mM.What is the rate-limiting step in the formation of an actin filament? Addition of actin monomers to an existing filament None of the above Initiation, or nucleation Cross-linking
- In cells, actin filaments form bundles or networks. How do cells form such structures, and what specifically determines whether actin filaments will form a bundle or a network?Select the correct statement regarding the actin cytoskeleton. They are involved in the formation of the axoneme. Actin microfilaments are the most stable cytoskeleton network. Can undergo catastrophe due to GTP hydrolysis-mediated conformational changes. Synthesis and degradation of actin microfilaments is directional, with g-actin subunits added only to the + end of the microfilament while depolymerization occurs at the - end. From the list below, select the correct statements regarding the genetic code. Codons code for 30 distinct amino acids. The basis of the genetic code are codons. The genetic code has a possible 64 different codons. The genetic code has built-in degeneracy. Codons are formed by 5 consecutive nucleotides.Several types of cells use the actin cytoskeleton to power their locomotion across surfaces. How are different assemblies of actin filaments involved in locomotion?
