Chapter 01: Cellular Biology
MULTIPLE CHOICE
1. A student is observing a cell under the microscope. It is observed to have supercoiled DNA
with histones. Which of the following would also be observed by the student?
a. A single circular chromosome
b. A nucleus
c. Free-floating nuclear material
d. No organelles
ANS: B
The cell described is a eukaryotic cell, so it has histones and a supercoiled DNA within its
nucleus; thus, the nucleus should be observed. A single circular chromosome called a
prokaryotecontains free-floating nuclear material but has no organelles.
REF: p. 2
2. A nurse is instructing the staff about cellular functions. Which cellular function is the
nurse describing when an isolated cell absorbs oxygen and uses it to transform nutrients to
energy?
a. Metabolic absorption
b. Communication
c. Secretion
d. Respiration
ANS: D
The cell’s ability to absorb oxygen is referred to as respiration while its communication ability
involves maintenance of a steady dynamic state, metabolic absorption provides nutrition, and
secretionallows for the synthesizing of new substances.
REF: p. 2
3. A eukaryotic cell is undergoing DNA replication. In which region of the cell would most of the
genetic information be contained?
a. Mitochondria

b. Ribosome
c. Nucleolus
d. Nucleus Cytoplasm
ANS: C
The region of the cell that contains genetic material, including a large amount of ribonucleic
acid, most of the DNA, and DNA-binding proteins, is the nucleolus, which is located within the
cell’s nucleus. Mitochondria is associated with cellular respiration, while ribosomes are
involved with protein manufacturing. Cytoplasm is a fluid filling that is a component of the
cell.
REF: p. 2
4. Which of the following can remove proteins attached to the cell’s bilayer by dissolving the layer
itself?
a. Peripheral membrane proteins
b. Integral membrane proteins
c. Glycoproteins
d. Cell adhesion molecules
ANS: B
Proteins directly attached to the membrane bilayer can be removed by the action of integral
membrane proteins that dissolve the bilayer. Peripheral membrane proteins reside at the
surface while cell adhesion molecules are on the outside of the membrane. Glycoprotein
markscells and does not float.
REF: p. 7
5. Which of the following can bind to plasma membrane receptors?
a. Oxygen
b. Ribosomes
c. Amphipathic lipids
d. Ligands
ANS: D
Ligands are the only specific molecules that can bind with receptors on the cell membrane.
REF: p. 9
6. A nurse is reviewing a report from a patient with metastatic cancer. What alternation in the
