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 bounded cellular components called organelles. No
organelles describes 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 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
