1. Which type of RNA carries amino acids to the ribosome?
A. mRNA
B. rRNA
C. tRNA
D. snRNA
Correct answer: C
Rationale: tRNA transfers specific amino acids to the growing
polypeptide during translation.
2. Which RNA is the template for protein synthesis?
A. mRNA
B. rRNA
C. tRNA
D. snRNA
Correct answer: A
,Rationale: mRNA carries genetic information from DNA to
ribosomes.
3. Which RNA forms the core of ribosome structure?
A. mRNA
B. rRNA
C. tRNA
D. snRNA
Correct answer: B
Rationale: rRNA combines with proteins to form ribosomes.
4. Which process converts DNA into RNA?
A. Replication
B. Translation
C. Transcription
D. Splicing
Correct answer: C
Rationale: Transcription synthesizes RNA using DNA as a template.
5. Which process converts mRNA into protein?
A. Replication
B. Translation
C. Transcription
,D. Splicing
Correct answer: B
Rationale: Translation reads mRNA codons to assemble amino
acids into proteins.
6. Which enzyme synthesizes RNA from DNA?
A. DNA polymerase
B. RNA polymerase
C. Ligase
D. Helicase
Correct answer: B
Rationale: RNA polymerase synthesizes RNA during transcription.
7. Which sequence signals the start of transcription?
A. Terminator
B. Promoter
C. Origin of replication
D. Enhancer
Correct answer: B
Rationale: The promoter region recruits RNA polymerase to begin
transcription.
8. Which nucleotide is replaced by uracil in RNA?
, A. Adenine
B. Thymine
C. Cytosine
D. Guanine
Correct answer: B
Rationale: RNA contains uracil instead of thymine.
9. Which part of DNA is removed during RNA splicing?
A. Exons
B. Introns
C. Codons
D. Promoters
Correct answer: B
Rationale: Introns are non-coding sequences removed from pre-
mRNA.
10. Which part of RNA remains after splicing?
A. Introns
B. Exons
C. Promoters
D. Codons
Correct answer: B
Rationale: Exons are joined to form mature mRNA.
