Power house or maybe protein pump if you are talking about cells in biology
Answer:
The correct answer is that the spliceosome is non-functional.
Explanation:
A spliceosome refers to a composite and large molecular apparatus found mainly inside the nucleus of the eukaryotic cells. The prime function of the spliceosome is to remove the introns from a transcribed pre-mRNA, that is, a kind of primary transcript.
In case if the spliceosome machinery gets failed to function, the mRNA will not remove the introns, that is, the non-coding parts and retains it. This will eventually lead to the formation of longer mRNAs.
