WGU Biochem C785: Unit 4 DNA and RNA Questions and Answers
with Verified Solutions | Latest 2026 Update
Q: How does mRNA splicing allow us to create multiple proteins from a single
gene/mRNA?
Answer:
During a typical gene splicing event, the pre-mRNA transcribed from one gene can
lead to different mature mRNA molecules that generate multiple functional proteins
Q: Primary Protein Structure
Answer:
Linear chain of amino acids
Q: Secondary Protein Structure
Answer:
Regions of stabilized hydrogen bonds between atoms of the
polypeptide back bone

Q: Tertiary Protein Structure
Answer:
Three-dimensional shape stabilized by interactions between side
chains
Q: Quaternary Protein Structure
Answer:
Association of two or more polypeptides

Q: How do factors of gene expression work together to control transcription?
Answer:
Q: Mutations
Answer:
Alterations in the DNA sequence
Q: Can be neutral or detrimental, leading to useless or less active protein that
impairs cellular
Answer:
function
Q: Nucleotide-Pair Substitution
Answer:
The replacement of one nucleotide and its partner with
another pair of nucleotides

Q: Point Mutations
Answer:
Changes in a single nucleotide pair of a gene (Base Substitutions, Deletions,
Insertions)
Q: Nonsense Mutations
Answer:
A mutation that changes an amino acid codon to a stop codons,
resulting in a shorter and usually nonfunctional protein from the premature stop of
translation
Q: Missense Mutations
Answer:
Substitutions that change one amino acid to another
