Additional amino acids would be inserted into the chain.

Answer 1

Additional amino acids would be inserted into the chain.

Explanation: Introns are normally spliced out of pre-mRNA before translation. If an intron is retained and translated, its codons would be read, adding extra (often disruptive) amino acids to the protein (and possibly introducing premature stop codons).
