Functions of Microfilaments - THE CORRECT ANSWER-Muscle
contraction, cell division, maintenance of cellular shape in
animal cells, Amoeboid movement, Cytoplasmic streaming
Nucleosome, 30-nm chromatin fiber, looped domain - THE
CORRECT ANSWER-Which of the following represents the order of
increasingly higher levels of organization of chromatin (30-nm
chromatin fiber, Looped domain, Nucleosome) ?
Addition of tubulin subunits to each end - THE CORRECT ANSWER-
Elongation of the microtubule occurs by the?
Centrosome - THE CORRECT ANSWER-The minus (-) ends of
microtubules are often anchored at the ________________ ,
such that the dynamics
associated with microtubules is at the plus (+) ends.
Role of Microfilaments - THE CORRECT ANSWER-Muscle cell
contraction, , , Cell migration.
, Moved by Molecular Motors - THE CORRECT ANSWER-What is in
common about Secretory vesicles, Cytoskeletal filaments, The
Golgi complex, Chloroplasts
Cis-Golgi and the Medial Golgi - THE CORRECT ANSWER-Which part
of the Golgi complex is closest to and sends material to the
plasma membrane?
* - THE CORRECT ANSWER-_________________ is the molecular
motor used by transport vesicles carrying cargo from the
plasma
membrane to the early endosome
Intermediate filaments - THE CORRECT ANSWER-Resist shear forces
and contain keratin to form the protective barrier of the skin.
Microvilli - THE CORRECT ANSWER-Actin bundles give shape and
support to the ________ found in cells of the small intestine.
Lamellipodia - THE CORRECT ANSWER-Are thin sheets of cytoplasm
used for cell movement
* - THE CORRECT ANSWER-What would happen to the movement of
vesicles toward their eventual target if a drug that promotes the
hydrolysis of GTP bound to tubulin was added to cells?
Outer doublets; central pair - THE CORRECT ANSWER-The "9 + 2"
pattern of the flagella is nine ________ of microtubules and
two additional microtubules in the center
