A mutation in a eukaryotic gene results in the production of a truncated protein lacking its C-terminal region. Analysis reveals a mutation within an intron of the gene. Which of the following is the MOST likely explanation?
The mutation disrupted a splicing enhancer sequence, leading to exon skipping.
The mutation created a new promoter within the intron.
The mutation disrupted the polyadenylation signal, preventing proper termination.
The mutation created a premature stop codon within the intron.
