Question

what would happen if a cell transcribed and translated a genes intron by mistake? (1 point)○ the dna would remain the same as before.○ the cell would begin to duplicate itself.○ additional amino acids would be inserted into the chain.○ errors in the protein folding would be repaired.

Explanation:

Introns are non-coding regions of a gene that are normally removed during RNA processing before translation. If an intron is mistakenly transcribed and translated, the cell will read its nucleotide sequence as coding information, which will be converted into additional amino acids added to the resulting protein. This alters the protein's structure and function. The other options are incorrect: the DNA sequence itself is not changed, the cell's replication is not directly affected, and this error does not trigger crossing over (a meiotic genetic recombination process).

Answer:

Additional amino acids would be inserted into the protein.
