Fillaments

Question 1

monomer of microfilaments

Answer 1

actin

Question 2

monomer of microtubules

Answer 2

tubulin

Question 3

protofilaments

Answer 3

13 linear polymers of tubulin that together form a hollow cylinder of microtubule

Question 4

large-scale polarity information

Answer 4

cytoskeletal filaments determine the polarity of the cell

ex. apical and basolateral surfaces of epithelial cells

Question 5

head-to-tail binding

Answer 5

tubulin and actin

Answer 9

intermediate

Question 10

FtsZ

Answer 10

tubulin homolog in prokaryotic cells

Question 11

Z-ring

Answer 11

formed from FtsZ filaments at the site of septum during prokaryotic cell division

Question 12

MreB and Mbl

Answer 12

actin homologs

Question 13

ParM

Answer 13

another actin homolog

but plasmid-encoded, separates newly replicated plasmids

Question 14

ParR

Answer 14

binds to certain DNA seqs and stabilized dynamic ends of ParM filaments

Question 15

TubZ

Answer 15

distant relative of tubulin and FtsZ

crescentin

Answer 16

homolog of intermediate filaments

Caulobacter crescentus
