,Chapter 1. Cellular Biology
MULTIPLE RESPONSES
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
CORRECT RESPONSE:-: 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 caregiver is instructing the staff about cellular functions. Which cellular function is the
caregiver describing when an isolated cell absorbs oxygen and uses it to transform nutrients to
energy?
a. Metabolic absorption
b. Communication
c. Secretion
d. Respiration
CORRECT RESPONSE:-: 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
, CORRECT RESPONSE:-: 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
c. Glycoproteins
d. Cell adhesion molecules
CORRECT RESPONSE:-: 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.
