Question

Which of the following is NOT involved in eukaryotic translation?

• A. Ribosome
• B. Spliceosome
• C. mRNA
• D. tRNA

Hint:

Translation uses ribosomes, mRNA, and tRNA. Splicing happens BEFORE translation and uses spliceosomes.

Answer 1

The Correct Option is B

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.
