identify the protein that is recognized by a specific antibody?
a) RNA sequencing
pg. 1
,b) Electron microscopy
c) Mass spec

You are studying a particular protein we'll cap YFP. You hypothesize that
YFP binds to tightly to other proteins in the cll and wish to identify those
proteins. Which technique discussed in lecture will most directly allow
you to achieve you goal?
a) Deletion analysis
b) A domain swapping experiment
c) Screening an expression library
d) A Co-immunoprecipitation experiment - Correct Answer – d).
Which family of cell-cell adhesion molecules has approximately 750
family members in humans and is thought to play a role in wiring of the
human brain?
a) Selections
b) Cadherins
c) Ig-CAMs
d) Integrins - Correct Answer - Ig-CAMs
Which type of junction prevents transmembrane proteins in the apical
part of the plasma membrane from diffusing into the basolateral part of
the plasma membrane?
pg. 2
,a) Equatorial junctions
b) Adherins junctions
c) Tight junctions
d) Gap junctions - Correct Answer - Tight junctions
Which type of junction effectively connects the intermediate filament
cytoskeleton of one cel to the intermediate filament cytoskeleton of an
adjacent cell?
a) Desmosome
b) Focal adhesion
c) Adherens junction
d) Hemidesmosome - Correct Answer - Desmosome
You are studying a cell line in which one cell cycle takes approx. 24
hours. You perform FACS analysis on a population of you dividing cells.
Your cells are growing asynchronously meaning different cells are in
different stages of the cell cycle. Your FACS analysis indicates that 1/3
of your cells have a DNA content 2n. How long is the G1 phase in these
cells?
a) 2 hours
b) 8 hours
c) 24 hours
d) 4 hours - Correct Answer - 8 hours
pg. 3

interphase cytoplasmic microtubules?
a) they are dimers
b) they are trimers
c) they are tetramers
d) they are monomers - Correct Answer - they are dimers
For animals that change color, which types of motor proteins are the
targets of neuronal signaling involved in color changes?
a) kinesins
b) dyneins
c) myosins
d) dyneins and kinesins - Correct Answer - dyneins and kinesins
For animals that change shape, which types of motor proteins are the
targets of neuronal signaling involved in changing shape
a) myosins
b) kinesins
c) dyneins
d) dyneins and kinesins - Correct Answer - myosins
Which of the following most accurately describes when in the cell cycle
the G1 Cdks are present and active?
