2. Most of a cell’s genetic information, including RNA and DNA, is
contained in the: a. Mitochondria c. Nucleolus b. Ribosome d.
Lysosome ANS: C The nucleus contains the nucleolus, a small dense
structure composed largely of RNA, most of the cellular DNA, and the
DNA-binding proteins, such as the histones, which regulate its activity.
The other options do not contain most of a cell’s genetic information.

1. Which statement best describes the cellular function of metabolic
absorption? a. Cells can produce proteins. c. Cells can take in and use
nutrients. b. Cells can secrete digestive enzymes. d. Cells can
synthesize fats. ANS: C In metabolic absorption, all cells take in and
use nutrients and other substances from their surroundings. The
