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.

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?
DR ERIC DR ERIC DR ERIC
,DR ERIC DR ERIC DR ERIC
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.

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.
