1. A student is observing a cell under the microscope. It is observed to have supe
x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@
rcoiled DNA with histones. Which of the following would also be observed by the st

udent?
a. A single circular chromosome
x@ x@ x@
b. A nucleus
x@
c. Free-floating nuclear material x@ x@
d. No organelles
x@
ANS: B x@
The cell described is a eukaryotic cell, so it has histones and a supercoiled DNA within
