ANS: C z+ z+


The nucleus contains the nucleolus, a small dense structure composed largely of RNA,
z+ z+ z+ z+ z+ z+ z+ z+ z+ z+ z+ z+ z+


most of the cellular DNA, and the DNA-
z+ z+ z+ z+ z+ z+ z+


binding proteins, such as the histones, which regulate its activity. The other options do

a. Lysosomes c. Ribosomes z+ z+ z+


b. Peroxisomes d. Oxyhydrosomes z+ z+ z+

ANS: B z+ z+


Peroxisomes are so named because they usually contain enzymes that use oxygen to re

move hydrogen atoms from specific substrates in an oxidative reaction that produces H2
z+ z+ z+ z+ z+ z+ z+ z+ z+ z+ z+ z+


O2, which is a powerful oxidant and potentially destructive if it accumulates or escapes

from peroxisomes. Ribosomes are RNA-
