MULTIPLE CHOICE
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 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 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
A nurse is instructing the staff about cellular functions. Which cellular function
is the nurse describing when an isolated cell absorbs oxygen and uses it to
transform nutrients to energy?
, Metabolic absorption
Communication
Secretion
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
, A eukaryotic cell is undergoing DNA replication. In which region of the cell
would most ofthe genetic information be contained?
Mitochondria
Ribosome
Nucleolus
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 withinthe 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.
