MODULE 1 EXAM 2025 QUESTIONS AND ANSWERS
True/False. A virus is classified as a microbe.
Correct! - ....ANSWER ...-True!
—
Although viruses are not living and as such are not considered microorganisms,
they can, however, be classified as microbes, a more general term that includes
microorganisms and viruses.
True or False: The smallest biological unit of life is the molecule. -
....ANSWER ...-False!
—
The smallest biological unit of life is the cell.
At a generalized level, all cells are comprised of what? - ....ANSWER ...-
macromolecules (proteins, lipids, nucleic acids, and polysaccharides)

,Proteins are formed from various combinations of _________ of which there are
_________ known forms. - ....ANSWER ...-amino acids 20
Define an essential amino acid. - ....ANSWER ...-An essential amino acid
cannot be produced by the human body and as such must be take in from the
environment through alternative sources (i.e) food.
Where can the two major types of nucleic acids be found in the cell, and what are
their roles? - ....ANSWER ...-While both DNA and RNA can be found in
the nucleus (center of the cell), only RNA is capable of leaving the nucleus. DNA
contains a vast amount of hereditary information and is responsible for the
inheritable characteristics of living organisms. RNA is responsible for deciphering
the hereditary information in DNA and using it to synthesize proteins.
Complete the following RNA strand, and indicate how many bonds are formed for
each complementary pair:
3' GGUCAUCG 5'
5' CC AGC 3' - ....ANSWER ...-3' GGUCAUCG 5'
5' CCAGUAGC 3'
There are 2 bonds formed between A and U, and 3 bonds between G and C.

, The plasma membrane (select all that are true): - ....ANSWER ...-Is often a
bilayer comprised of lipids
Contains hydrophobic tails pointing inward
Carbon, hydrogen, and oxygen atoms come together to form what primary
macromolecule? Give an example. - ....ANSWER ...-Polysaccharides
(carbohydrates). Any sugar is acceptable: Glucose, sucrose, fructose, galactose,
lactose, maltose, etc.
Also options: Starch, glycogen, cellulose, or chitin
True of False: The genetic material within a prokaryotic cell is contained within a
membrane-enclosed region. - ....ANSWER ...-False!
—
Only eukaryotic cells contain its genetic material within a nucleus
Describe the 4 basic bacterial morphologies. - ....ANSWER ...-Coccus
(round/spherical), bacillus (rod), vibrio (curved rod) or spirillum
(spiral/corkscrew).
True or False: Archaea is noted for its ability to survive under harsh conditions -
....ANSWER ...-True!
