MULTIPLE CHOICE
1. A student is observing a cell under the microscope. It is observed to have supercoiled DNA with histones. Which
of the following would also be observed by the student?
a. A single circular chromosome
b. A nucleus
c. Free-floating nuclear material
d. No organelles
ANS: B
The cell described is a eukaryotic cell, so it has histones and a supercoiled DNA within its nucleus; thus, the
nucleus should be observed. A single circular chromosome called a prokaryote contains free-floating nuclear
material but has no organelles.
REF: p. 2
2. A nurse isinstructing the staff about cellular functions. Which cellular function isthe nurse describing when an
isolated cell absorbs oxygen and uses it to transform nutrients to energy?
a. Metabolic absorption
b. Communication
c. Secretion
d. Respiration
ANS: D
The cell’s ability to absorb oxygen is referred to as respiration while its communication ability involves
maintenance of a steady dynamic state, metabolic absorption provides nutrition, and secretion allows for the
synthesizing of new substances.
REF: p. 2
3. A eukaryotic cell is undergoing DNA replication. In which region of the cell would most of the genetic information
be contained?
a. Mitochondria
b. Ribosome
c. Nucleolus
d. Nucleus Cytoplasm
ANS: C
The region of the cell that contains genetic material, including a large amount of ribonucleic acid, most of the
DNA, and DNA-binding proteins, is the nucleolus, which is located within the cell’s nucleus. Mitochondria is
associated with cellular respiration, while ribosomes are involved with protein manufacturing. Cytoplasm is a
fluid filling that is a component of the cell.
