MULTIPLE CHOICES N
1. A student is observing a cell under the microscope. It is observed to have supercoiled DNA
N N N N N N N N N N N N N N N N
with histones. Which of the following would also be observed by the student?
N N N N N N N N N N N N
a. A single circular chromosome
N N N
b. A nucleus N
c. Free-floating nuclear material N N
d. No organelles N
ANS: B N
The cell described is a eukaryotic cell, so it has histones and a supercoiled DNA within its
N N N N N N N N N N N N N N N N N
nucleus; thus, the nucleus should be observed. A single circular chromosome called a prok
N N N N N N N N N N N N N
aryote contains free-floating nuclear material but has no organelles.

N N N N N N N N N N N N N N N
describing when an isolated cell absorbs oxygen and uses it to transform nutrients to energy?
N N N N N N N N N N N N N N
a. Metabolic absorption N
b. Communication
c. Secretion
d. Respiration
ANS: D N

The cell’s ability to absorb oxygen is referred to as respiration while its communication ability
N N N N N N N N N N N N N N N
involves maintenance of a steady dynamic state, metabolic absorption provides nutrition, and s
N N N N N N N N N N N N
ecretion allows for the synthesizing of new substances.

3. A eukaryotic cell is undergoing DNA replication. In which region of the cell would most of
N N N N N N N N N N N N N N N N
the genetic information be contained?
N N N N
a. Mitochondria
b. Ribosome
c. Nucleolus
d. Nucleus Cytoplasm N
ANS: C N
The region of the cell that contains genetic material, including a large amount of ribonucleic
N N N N N N N N N N N N N N N
acid, most of the DNA, and DNA-
N N N N N N
binding proteins, is the nucleolus, which is located withinthe cell’s nucleus. Mitochondria is

4. Which of the following can remove proteins attached to the cell’s bilayer by dissolving the
N N N N N N N N N N N N N N N
layer itself? N
a. Peripheral membrane proteins N N
b. Integral membrane proteins N N
c. Glycoproteins
d. Cell adhesion molecules N N
ANS: B N
Proteins directly attached to the membrane bilayer can be removed by the action of integral
N N N N N N N N N N N N N N N
membrane proteins that dissolve the bilayer. Peripheral membrane proteins reside at the surf
N N N N N N N N N N N N
ace while cell adhesion molecules are on the outside of the membrane. Glycoprotein marks

N N N N N
a. Oxygen
b. Ribosomes

N N N N
a. Decreased fibronectin N
b. Increased collagen N
c. Decreased elastin N

ANS: A N
Only a reduced amount of fibronectin is found in some types of cancerous cells, allowing
N N N N N N N N N N N N N N N
them to travel or metastasize.

7. Which form of cell communication is used to relate to other cells in direct physical contact?
N N N N N N N N N N N N N N N
a. Cell junction N
b. Gap junction N
c. Desmosome
d. Tight junction N
ANS: A N
Cell junctions hold cells together and permit molecules to pass from cell to cell.
N N N N N N N N N N N N N
Gap junctions allow for cellular communication between cells. Neither desmosomes nor tight
N N N N N N N N N N N N
junctions are associated with cellular communication.
