If a cell accidentally transcribed and translated a gene's intron by mistake, the most relevant consequence would be:
• Additional amino acids would be inserted into the chain.
Introns are non-coding sequences that typically do not contribute to the final protein product, as they are usually spliced out during RNA processing. However, if an intron were to be translated into the protein, it would likely introduce non-functional or misfolded segments with additional amino acids that would not normally be present in the functional protein.
