BIOD 171 M1: Module 1 Exam | Latest Updated 2026/2027 (Graded A+)
T/F: A virus is considered a microorganism ✔️False.
Viruses are not living and are therefore not considered microorganisms. Viruses can be classified as microbes (a more general term that
includes microorganisms and viruses).
What is the smallest biological unit of life? ✔️A cell
At a generalized level, all cells are comprised of what? ✔️macromolecules
How many different types of amino acids are available from which to make proteins? ✔️20
Define an essential amino acid. ✔️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? ✔️DNA and RNA can both be found in the nucleus,
but only RNA is able to leave the nucleus.
- DNA contains a large 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 DNA strand, and indicate how many bonds are
formed for each complementary pair:
3' GGTCATCG 5'
5' CC AGC 3' ✔️3' GGTCATCG 5'
5' CCAGTGC 3'
There are 2 bonds formed between A and T, and 3 bonds between G and C.
The plasma membrane (select all that are true):
A. Only restricts movement of materials into the cell.
B. Is often a bilayer comprised of lipids.
C. Cannot prevent essential nutrients from escaping.
D. Contains hydrophobic tails pointing inward. ✔️B. Is often a bilayer comprised of lipids
D. Contains hydrophobic tails pointing inward
How many carbon atoms are present in glucose? ✔️6.
The molecular formula of Glucose is C6H12O6
T/F: The genetic material within a prokaryotic cell is contained within a membrane-enclosed region. ✔️False.
T/F: A virus is considered a microorganism ✔️False.
