Question
Microfilaments and microtubules are cytoskeletal elements that also function in the cell shape and cell movements. Determine whether each of the following statements describes microfilaments, microtubules or both?a. Dimers polymerize into protofilametns that then associate side by side
b. monomers bind GTP
c. 13 Protofilaments associate to form a hollow tube
d. Monomers bind ATP
e. Polymer of globular subunits
f. all the nucleotide-binding sites point the same direction.
g. fibers polymerize and depolymerize quickly
h. structure is a double chain of subunits
Explanation / Answer
THIS IS THE SOLUTION SAPLING GAVE ME AFTER I GAVE UP a. Dimers polymerize into protofilametns that then associate side by side Microtubules b. monomers bind GTP Microtubules c. 13 Protofilaments associate to form a hollow tube Microtubules d. Monomers bind ATP Microfilaments e. Polymer of globular subunits Microfilaments and Microtubule f. all the nucleotide-binding sites point the same direction. Microfilaments and Microtubules g. fibers polymerize and depolymerize quickly Microfilaments and Microtubules h. structure is a double chain of subunits Microfilaments
