Chapter 1. Cellular Biology
MULTIPLE CHOICE
1. A student is observing a cell under the microscope. It is observed to have
supercoiled DNAwith 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 itsnucleus; 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 distinctnucleus.
Eukaryotic cells have membrane bounded cellular components called organelles.
No organellesdescribes a prokaryotic cell.

2. A nurse is instructing the staff about cellular functions. Which cellular
function is the nursedescribing when an isolated cell absorbs oxygen and uses
it to transform nutrients to energy?
a. Metabolic absorption
b. Communication
c. Secretion
d. Respiration
, NURS PATHO TEST BANK
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 ofcommunication.
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 cellsfunction of secretion.
3. A eukaryotic cell is undergoing DNA replication. In which region of the cell
would most ofthe 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 ribonucleicacid, most of the DNA, and DNA-binding proteins, is the
nucleolus.
The mitochondria is the site of cellular respiration.
The ribosomes are involved in 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
, NURS PATHO TEST BANK
behavior. According tothis model, which of the following float singly or as
aggregates in the fluid lipid bilayer?
a. Peripheral membrane proteins
b. Integral membrane proteins
