Microtubules are generally nucleated from a specific intracellular location known as a
microtubule-organization center (MTOC). Animal cells have a single, well-defined
MTOC called the _____, located near the nucleus.It consists two barrel-shaped _____ that
are embedded in an amorphous matrix of fibrous proteins (pericentriolar material)
where the ____-___ ring complexes are attached.

All IF proteins have a very highly conserved central rod ____. Variations in the head (____
terminus) and tail (_____ terminus) regions of the proteins differentiate the subfamilies of
IFproteins.

_____ are rapidly assembled and dissembled during cell division and form a stable array
structure in ____ cells.

True or false? EB-1 moves toward plus ends of MTs.
Give this one a try later!
, False, EB-1 does not move toward plus ends, but recognizes a structural
feature of the growing positive end. EB-1 mediates the interaction with
other proteins

The microtubule is stabilized by the ____ interaction between monomer of the same
type (alpha-alpha and beta- beta). A slight stagger (0.9 nm) in lateral contacts
produce a helical structure, which accommodates 13 _____. This microtubule
organization gives intrinsic ____ (plus end and minus end), and make the addition and
loss of subunits almost exclusively occur at the microtubule ends.
