Answer :
The spliceosome, which operates in the nucleus, removes intronic sequences from RNA molecules.
What prevents intron translation?
Because they are spliced out during RNA splicing, introns are not regarded as untranslated regions. The introns are thought of as non-protein-coding RNA as they are not a part of the mature mRNA molecule that will be translated.
Intronic sequences are eliminated from RNA molecules by the spliceosome, a cell's nucleus-based enzyme.
Therefore, Intronic sequences are frequently codified in the DNA of genes in eukaryotic cells.
