Chapter 1. Cellular Biology
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 is characteristic of prokaryotic cells, which do
not have histones.
Free-floating nuclear material describes a prokaryotic cell, which would not
have a distinct nucleus.
Eukaryotic cells have membrane bounded cellular components called
organelles. No organelles describes a prokaryotic cell.
