PATHOPHYSIOLOGY: MODULE 3 QUESTIONS AND
ANSWERS 2024/2025 UPDATED STUDY GUIDE
1. DNA contains:
a. the enzymes necessary for cell division.
b. the genetic code for all parts of the body.
c. a genetic blueprint for making proteins only.
d. proteins for structural elements in the cell.: b. the genetic code
for all parts of the body.
The genetic code for all structural elements in the body is contained
in the DNA.
2. Adenine, cytosine, guanine, and thymine are:
a. phosphate groups
b. amino acids
c. the four helical strands of DNA
d. nitrogen bases: d. nitrogen bases
Adenine, cytosine, guanine, and thymine are nitrogenous bases. The
nitrogenous bases make up the "rungs" of the ladder of DNA. Each
rung is made up of a pair of bases that are bound together by a weak
hydrogen bond.
3. The triplet of base pairs necessary to code for a specific
amino acid is called a:
a. protein
b. nucleotide
c. codon
d. chromosome.: c. codon
4. The base components of RNA are:
, PATHOPHYSIOLOGY: MODULE 3 QUESTIONS AND
ANSWERS 2024/2025 UPDATED STUDY GUIDE
a. A, G, C, and U
b. U, G, C, and T
c. A, G, C, and T
D. X and Y: a. A, G, C, and U
The base components of RNA are A (adenine), G (guanine), C
(cytosine), and U (uracil).
5. In the DNA helix, guanine pairs with: Cytosine
6. Transcription: The process by which RNA is formed from DNA
for protein synthesis
7. Translation: process by which mRNA interacts with tRNA in the
ribosome.
8. Mitosis: process of DNA replication and cell division
9. Meiosis: when cell division occurs without replication of DNA
contents.
10.Prior to translation, which of the following steps must occur
a. Anticodon on tRNA matches its codon on mRNA
b. Peptide binding of amino acid sequences
c. DNA unzipping and complementary base pairing
d. Ribosome reading of the termination sequence on mRNA: c.
DNA unzipping and complementary base pairing
Prior to translation, DNA unzips to allow for complementary base pairing
and formation of mRNA.
1 1. Mutations can result in abnormal:
a. DNA
b. RNA
c. proteins
