What is the function of the cytoskeleton in eukaryotic cells?
multiple can be selected
Move chromosomes during cell division
Maintain cell shape by resisting tension
Anchor the nucleus and some other organelles
Divide animal cells in two
Solutions
Expert Solution
All are correct
- Move chromosomes during cell division : microtubules
- Maintain cell shape by resisting tension : intermediate filaments
- Anchor the nucleus and some other organelles : intermediate filaments (example, nuclear lamina)
- Divide animal cells in two : actin filaments
Please rate high.

Vesicles in eukaryotic cells can move along microtubules, using
the ATPases kinesin and dynein. The figure at right depicts a
microtubule aster nucleated from a centrosome, with a transport
vesicle moving along the microtubule. The + and – ends of that
microtubule are indicated.
A. Which microtubule motor protein would be used to transport
the vesicle away from the centrosome?
B. Which motor protein do you think would power:
1. Vesicle transport from the ER to the Golgi?
2. Vesicle...

35.
The chromosomes in eukaryotic cells are composed by structures
called nucleosomes (?beads on a string?) which contribute to the
chromosomal highly condensed nature. Find the incorrect
statement.
A.
Histone proteins in nucleosomes are octameric cores 2*(H2A + H2B
+ H3+ H4) and a single H1.
B.
Eukaryotic chromosomes are composed of circular DNA molecules
with proteins rich in acid amino acyl residues (e.g. aspartic acid
and glutamic acid).
C.
Histones can be chemically modified by phosphorylation,
methylation and acetylation....
