A eukaryotic protein-encoding gene contains two introns and three exons: exon 1-intron 1-exon 2-intron 2-exon 3. The 5 splice site at the boundary between exon 2 and intron 2 has been eliminated by a small deletion in the gene. Describe how the pre-mRNA encoded by this mutant gene would be spliced. Indicate which introns and exons would be found in the mRNA after splicing occurs.
