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.
