Answers: -
a. Dimers polymerize into protofilametns that then associate side by side - Microfilament
b. monomers bind GTP - Microtubule
c. 13 Protofilaments associate to form a hollow tube - Microtubule.
d. Monomers bind ATP - Microfilament.
e. Polymer of globular subunits - Microfilament.
f. all the nucleotide-binding sites point the same direction - Microfilament
g. fibers polymerize and depolymerize quickly - Microfilament and Microtubule.
h. structure is a double chain of subunits- Microfilament.
