Question:
Which of the following is NOT involved in eukaryotic translation?
Which of the following is NOT involved in eukaryotic translation?
Show Hint
Translation uses ribosomes, mRNA, and tRNA. Splicing happens BEFORE translation and uses spliceosomes.
Updated On: Dec 14, 2025
- Ribosome
- Spliceosome
- mRNA
- tRNA
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding translation.
Eukaryotic translation involves ribosomes, mRNA, tRNA, and various initiation, elongation, and termination factors. Its purpose is to synthesize proteins from mRNA. Spliceosomes, however, function during RNA processing — not translation.
Step 2: Analyzing the options.
(A) Ribosome: Required for translation.
(B) Spliceosome: Correct — it removes introns during mRNA processing before translation.
(C) mRNA: Template for protein synthesis.
(D) tRNA: Brings amino acids to the ribosome.
Step 3: Conclusion.
Spliceosomes are not part of the translation machinery, so option (B) is correct.
