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

2. A h u nurse is instructing the staff about cellular functions. Which
h u h u h u h u h u h u h u h u
h u cellular function hu h u is the nurse describing when an isolated cell
h u h u hu hu hu h u h u
h u absorbs oxygen and uses it to transform(rnutrients to energy?
h u h u hu h u hu hu h u h u
,a. Metabolic absorption hu
b. Communication
c. Secretion
d. Respiration
ANS: h u D
The cell’s ability to absorb oxygen is referred to as respiration
h u h u h u h u h u h u h u h u h u h u
h u while its communication abilityinvolves maintenance of a steady
h u hu h u h u h u h u h u
h u dynamic state, metabolic(rabsorption
h u hu h u provides nutrition, and secretion
h u h u h u
h u allows for the synthesizing of new substances.

REF: h u p. 2 h u
, 3. A h u eukaryotic cell is undergoing DNA replication. In which region
h u h u h u hu h u h u h u h u
h u of the cell would(rmost ofthe genetic information be contained?
h u hu hu h u h u h u h u h u
a. Mitochondria
b. Ribosome
c. Nucleolus
d. Nucleus Cytoplasm hu
ANS: h u C
The region of the cell that contains genetic material, including a
h u h u h u h u h u h u h u h u h u h u
h u large amount of ribonucleicacid,
h u hu h u h u most of the DNA, and DNA-
h u h u h u h u h u
binding proteins, is the nucleolus, which is located withinthe cell’s
h u h u h u hu h u h u h u h u h u
h u nucleus. Mitochondria is associated with cellular respiration, while
h u h u h u hu h u h u h u
h u ribosomes are involved with protein manufacturing. Cytoplasm is(ra
h u h u h u h u hu h u h u
h u fluid filling that is a component of the cell.
