MULTIPLE CHOICE u




1. A studentu u is observing a cell under the microscope. It is
u u u u u u u u




u observed to havesupercoiled DNAwith histones. Which of the following
u u u u u u u u




u would also be observed bythe student?
u u u u u



a. A single circular chromosome
u u u



b. A nucleus u



c. Free-floating nuclear material u u



d. No organelles u




ANS: B u




The cell described is a eukaryotic cell, so it has histones and a
u u u u u u u u u u u u




u supercoiled DNA within itsnucleus; thus, the nucleus should be observed. A
r u u u u u u u u u




u single circular chromosome called a prokaryote contains free-floating nuclear
u u u u u u u u




u material but hasno organelles. u u u




REF: p. 2 u u




2. A nurse is instructing the staff about cellular functions. Which cellular
u u u u u u u u u u




u function is the nurse describing when an isolated cell absorbs
u u u u u u u u u




u oxygen and uses it to transformnutrients to energy?
u r u u u u u

,a. Metabolic absorption u



b. Communication
c. Secretion
d. Respiration

ANS: D u




The cell’s ability to absorb oxygen is referred to as respiration
u u u u u u u u u u




u while itscommunication abilityinvolves maintenance of a steady dynamic
u u u u u u u




u state,metabolic(ra bsorption provides nutrition, and secretion allows for the
r ur u u u u u u u u




u synthesizing of new substances.
u u u




REF: p. 2

, 3. A eukaryotic cell is undergoing DNA replication. In which region of the
u u u u u u u u u u u




u cell w o u l d rm
u r ur ur ost ofthe genetic information be contained?
u u u u u



a. Mitochondria
b. Ribosome
c. Nucleolus
d. Nucleus Cytoplasm u




ANS: C u




The region of the cell that contains genetic material, including a
u u u u u u u u u u




u large amount of ribonucleicacid, most of the DNA, and DNA-binding
u u u u u u u u u




u proteins, is the nucleolus, which is located withinthe cell’s nucleus.
u u u u u u u u u




u Mitochondria is associatedwith cellular respiration, while ribosomes are
u u u u u u u




u involved with protein manufacturing. Cytoplasm isa fluid filling that is a
u u u u u u u u u u




u component of the cell. u u u
