1. A w student is observing a cell under the microscope. It is
w w w w w w w w w
w observed to havesupercoiled DNAwith histones. Which of the
w w w w w w w
w following would also be observed bythe student?
w w w w w w
a. A single circular chromosome
w w w
b. A nucleus w
c. Free-floating nuclear material w w
d. No organelles w
ANS: w B
The cell described
w w w is a eukaryotic cell, so
w w w w w it has histones and
w w w
w a supercoiled DNA within itsnucleus; thus, the nucleus should be observed.
w r w w w w w w w w
w A single circular chromosome called a prokaryote contains free-floating
w w w w w w w w
w nuclear material but hasno organelles.

2. A nurse is instructing the staff about cellular functions. Which cellular
w w w w w w w w w w
w function is the nurse describing when an isolated cell absorbs
w w w w w w w w w
w oxygen and uses it to transformnutrients to energy?
w r w w w w w
,a. Metabolic absorptionw
b. Communication
c. Secretion
d. Respiration
ANS: w D
The cell’s ability to absorb oxygen
w w w w w w is referred to as respiration
w w w w
w while itscommunication abilityinvolves maintenance of a steady dynamic
w w w w w w w
state,metabolic(ra
w r wr w bsorption provides nutrition, and secretion allows for the
w w w w w w w
synthesizing of new substances.

, 3. A eukaryotic cell is undergoing DNA
w w w w w w replication. In which region of w w w w
w the cell w o u l d rm ost ofthe genetic information be contained?
w w r wr wr w w w w w
a. Mitochondria
b. Ribosome
c. Nucleolus
d. Nucleus Cytoplasm w
ANS: w C
The region of the cell that
w w w w w w contains genetic material, including a
w w w w
w large amount of ribonucleicacid, most of the DNA, and DNA-binding
w w w w w w w w w
w proteins, w is the nucleolus, which is located withinthe cell’s nucleus.
w w w w w w w w
w Mitochondria is associatedwith cellular respiration, while ribosomes are
w w w w w w w
w involved with protein manufacturing. Cytoplasm isa fluid filling that is a
w w w w w w w w w w
