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 is characteristic of prokaryotic cells, which do not
have histones. Free-floating nuclear material describes a prokaryotic cell, which would not have a distinct
nucleus. Eukaryotic cells have membrane- bound cellular components called organelles. No organelles
describe a prokaryotic cell.
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 ability of the cell to absorb oxygen refers to the cells function of respiration. The ability of the cell to
function within a society of cells refers to its function of communication. The ability of the cell to take in
nutrients refers to the cells function of metabolic absorption.The ability of the cell to synthesize new
substances and secrete these elsewhere refers to the cells function of secretion.

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
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. The mitochondria is the site of cellular respiration. The
ribosomes are involved in the manufacturing of proteins within the cell. The nucleus contains the nucleolus,
and it is the nucleolus that contains genetic material.
4. The fluid-mosaic model for biologic membranes describes membrane behavior.
According to this model, which of the following float singly or as aggregates in the fluid lipid
bilayer?
a. Peripheral membrane proteins
b. Integral membrane proteins
c. Glycoproteins
d. Cell adhesion molecules
ANS: B
Integral membrane proteins float freely in the fluid lipid bilayer. Peripheral membrane proteins are not
embedded in the layer, but reside at the surface. Glycoproteins act as cell surface markers. Cell adhesion
molecules are on the outside of the membrane and allow cells to hook together.
