Chapter 1 - The Foundations of Biochemistry
1. In a bacterial cell, the DNA is in the:
A) cell envelope.
B) cell membrane.
C) nucleoid.
D) nucleus.
E) ribosomes.
2. A major change occurring in the evolution of eukaryotes from prokaryotes was the
development of:
A) DNA.
B) photosynthetic capability.
C) plasma membranes.
D) ribosomes.
E) the nucleus.
3. In eukaryotes, the nucleus is enclosed by a double membrane called the:
A) cell membrane.
B) nuclear envelope.
C) nucleolus.
D) nucleoplasm.
E) nucleosome.
4. The dimensions of living cells are limited, on the lower end by the minimum number of
biomolecules necessary for function, and on the upper end by the rate of diffusion of
solutes such as oxygen. Except for highly elongated cells, they usually have lengths and
diameters in the range of:
A) 0.1 m to 10 m.
B) 0.3 m to 30 m.
C) 0.3 m to 100 m.
D) 1 m to 100 m.
E) 1 m to 300 m.
5. Which group of single-celled microorganisms has many members found growing in
extreme environments?
A) bacteria
B) archaea
C) eukaryotes
D) heterotrophs
E) None of the answers is correct.

through noncovalent interactions. Which one of the following is NOT considered a
noncovalent interaction?
A) carbon-carbon bonds
B) hydrogen bonds
C) hydrophobic interactions
D) ionic interactions
