(Q017) Which of the mitochondrion
following organelles has
both an outer and an inner
membrane?
a.endoplasmic reticulum
b.mitochondrion
c.lysosome
d.peroxisome
The nucleus, an organelle chromosomes
found in eukaryotic cells,
confines the______,
keeping them separated
from other components of
the cell.
a.lysosomes
b.chromosomes
c.peroxisomes
d.ribosomes
,(Q037) Caenorhabditis programmed cell death.
elegans is a nematode.
During its development, it
produces more than 1000
cells. However, the adult
worm has only 959
somatic cells. The process
by which 131 cells are
specifically targeted for
destruction is called
a.directed cell pruning.
b. programmed cell death.
c.autophagy.
d. necrosis.
Prokaryotic cells do not nucleus
possess a..
a.nucleus.
b. replication machinery.
c. ribosomes.
d. membrane bilayers.
(Q005) Changes in DNA evolution.
sequence from one
generation to the next
may result in offspring that
are altered in fitness
compared with their
parents. The process of
change and selection over
the course of many
generations is the basis of
a.mutation.
b. evolution.
c. heredity.
d. reproduction.
,(Q002) The central dogma replication, transcription, translation
provides a framework for
thinking about how
genetic information is
copied and used to
produce structural and
catalytic components of
the cell. From the choices
below, select the order of
biochemical processes
that best correlates with
the tenets of the central
dogma.
a. replication,
transcription, translation b.
replication, translation,
transcription c. translation,
transcription, replication d.
translation, replication,
transcription
, (Q010) Cell biologists wavelength
employ targeted
fluorescent dyes or
modified fluorescent
proteins in both standard
fluorescence microscopy
and confocal microscopy
to observe specific details
in the cell. Even though
fluorescence permits
better visualization, the
resolving power is
essentially the same as
that of a standard light
microscope because the
resolving power of a
fluorescent microscope is
still limited by the __________
of visible light.
a.absorption
b. intensity
c.filtering
d. wavelength
Which of the following digestion of prey, clean-up, recycling, and disposal of
choices BEST describes macromolecules
the role of the lysosome?
a.transport of material to
the Golgi apparatus
b.digestion of prey, clean-
up, recycling, and disposal
of macromolecules
c. sorting of transport
vesicles
d. the storage of excess
macromolecules
