MULTIPLE CHOICE
• 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 single circular chromosome
• A nucleus
• Free-floating nuclear material
• 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.
• 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?
, • Metabolic absorption
• Communication
• Secretion
• 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 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.
• A eukaryotic cell is undergoing DNA replication. In which region of the
cell would most ofthe genetic information be contained?
• Mitochondria
• Ribosome
• Nucleolus
• 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.
