MULTIPLE CHOICE m




1. A student is observing a cell under the microscope. It is observed to have
m m m m m m m m m m m m m


msupercoiled DNA with histones. Which of the following would also be observed by the
m m m m m m m m m m m m m


mstudent?
a. A single circular chromosome
m m m




b. A nucleus
m




c. Free-floating nuclear material m m




d. No organelles
m




ANS: B m




The cell described is a eukaryotic cell, so it has histones and a supercoiled DNA within its
m m m m m m m m m m m m m m m m


mnucleus; thus, the nucleus should be observed. A single circular chromosome is characteristic
m m m m m m m m m m m m


mof prokaryotic cells, which do not have histones. Free-floating nuclear material describes a
m m m m m m m m m m m m


mprokaryotic cell, which would not have a distinct nucleus. Eukaryotic cells have membrane-
m m m m m m m m m m m m


mbound cellular components called organelles. No organelles describe a prokaryotic cell.
m m m m m m m m m m




2. A nurse is instructing the staff about cellular functions. Which cellular function
m m m m m m m m m m m


mis the nurse describing when an isolated cell absorbs oxygen and uses it to
m m m m m m m m m m m m m


mtransform nutrients to energy? m m m




a. Metabolic absorption m




b. Communication
c. Secretion
d. Respiration

ANS: D m




The ability of the cell to absorb oxygen refers to the cells function of respiration. The
m m m m m m m m m m m m m m m


mability of the cell to function within a society of cells refers to its function of
m m m m m m m m m m m m m m m


mcommunication. The ability of the cell to take in nutrients refers to the cells function of
m m m m m m m m m m m m m m m


mmetabolic absorption.The ability of the cell to synthesize new substances and secrete these
m m m m m m m m m m m m


melsewhere refers to the cells function of secretion.

3. A eukaryotic cell is undergoing DNA replication. In which region of the cell
m m m m m m m m m m m m



mwould most of the genetic information be contained?
m m m m m m m




a. Mitochondria
b. Ribosome
c. Nucleolus
d. Nucleus

ANS: C m




The region of the cell that contains genetic material, including a large amount of ribonucleic
m m m m m m m m m m m m m m


macid, most of the DNA, and DNA-binding proteins, is the nucleolus. The mitochondria is the
m m m m m m m m m m m m m m


msite of cellular respiration. The ribosomes are involved in the manufacturing of proteins
m m m m m m m m m m m m


mwithin the cell. The nucleus contains the nucleolus, and it is the nucleolus that contains
m m m m m m m m m m m m m m


mgenetic material.

4. The fluid-mosaic model for biologic membranes describes membrane
m m m m m m m


mbehavior. According to this model, which of the following float singly or as
m m m m m m m m m m m m


maggregates in the fluid lipid bilayer?
m m m m m




a. Peripheral membrane proteins m m




b. Integral membrane proteins
m m




c. Glycoproteins
d. Cell adhesion molecules
m m




ANS: B m




Integral membrane proteins float freely in the fluid lipid bilayer. Peripheral membrane proteins
m m m m m m m m m m m m


mare not embedded in the layer, but reside at the surface. Glycoproteins act as cell surface
m m m m m m m m m m m m m m m


mmarkers. Cell adhesion molecules are on the outside of the membrane and allow cells to
m m m m m m m m m m m m m m


mhook together.
