Answer 1

The correct response is: Additional amino acids would be inserted into the chain.

Explanation:

If a cell mistakenly transcribes and translates an intron (which is usually spliced out during RNA processing), the resulting mRNA would contain sequences that do not code for functional parts of the protein. When this RNA is translated, it could lead to the insertion of additional amino acids into the protein chain, depending on the sequence of the intron. This can result in a nonfunctional or dysfunctional protein, as the protein may misfold or have an altered structure due to the presence of these unintended amino acids.

To summarize:

• Introns are typically spliced out before translation, so their inclusion would disrupt the normal protein-coding sequence.
• This can lead to abnormal protein products with additional amino acids, which can affect the protein's function.
