Multiple Choice Questions (30 Questions)
s1 s1 s1 s1
1. Which nitrogenous base is found exclusively in RNA and replaces thymine found
s1 s1 s1 s1 s1 s1 s1 s1 s1 s1 s1 s1
s1 in DNA?
s1
a) Adenine
s1
b) Guanine
s1
c) Cytosine
s1
d) Uracil
s1
Answer: d) Uracil s1 s1
Explanation: Uracil is present in RNA instead of thymine. It pairs with adenine during
s1 s1 s1 s1 s1 s1 s1 s1 s1 s1 s1 s1 s1
s1 transcription. This difference is critical for distinguishing RNA from DNA in diagnostic
s1 s1 s1 s1 s1 s1 s1 s1 s1 s1 s1
s1 assays and for RNA stability/function.

2. The backbone of a DNA strand consists of alternating:
s1 s1 s1 s1 s1 s1 s1 s1 s1
a) Bases and sugars
s1 s1 s1
b) Phosphates and bases
s1 s1 s1
c) Sugars and phosphates
s1 s1 s1
d) Nitrogenous bases and hydrogen bonds
s1 s1 s1 s1 s1
, Answer: c) Sugars and phosphates
s1 s1 s1 s1
*Explanation: The sugar-phosphate backbone is formed by phosphodiester bonds
s1 s1 s1 s1 s1 s1 s1 s1
s1 between the 3' carbon of one deoxyribose and the 5' carbon of the next. This
s1 s1 s1 s1 s1 s1 s1 s1 s1 s1 s1 s1 s1 s1
s1 structure provides stability and directionality (5'→3') essential for replication and
s1 s1 s1 s1 s1 s1 s1 s1 s1
s1 transcription.*
3. Which type of RNA carries amino acids to the ribosome during protein synthesis?
s1 s1 s1 s1 s1 s1 s1 s1 s1 s1 s1 s1 s1
a) mRNA
s1
b) rRNA
s1
c) tRNA
s1
d) snRNA
s1
Answer: c) tRNA s1 s1
*Explanation: Transfer RNA (tRNA) has an anticodon that base-pairs with mRNA
s1 s1 s1 s1 s1 s1 s1 s1 s1 s1
s1 codons and carries a specific amino acid at its 3' end. This adaptor function is
s1 s1 s1 s1 s1 s1 s1 s1 s1 s1 s1 s1 s1 s1
s1 fundamental to translation accuracy in diagnostic protein analysis.*
s1 s1 s1 s1 s1 s1 s1
4. The primary structure of a protein refers to its:
s1 s1 s1 s1 s1 s1 s1 s1 s1
a) Three-dimensional folded shape
s1 s1 s1
b) Alpha helix and beta sheet arrangements
s1 s1 s1 s1 s1 s1
c) Linear sequence of amino acids
s1 s1 s1 s1 s1
d) Subunit assembly pattern
s1 s1 s1
Answer: c) Linear sequence of amino acids
s1 s1 s1 s1 s1 s1
Explanation: Primary structure is the covalent backbone of amino acids linked by
s1 s1 s1 s1 s1 s1 s1 s1 s1 s1 s1
s1 peptide bonds. This sequence determines higher-order folding and is directly encoded
s1 s1 s1 s1 s1 s1 s1 s1 s1 s1
s1 by genes, making it targetable by DNA sequencing in molecular diagnostics.
