Question 2a. The cartoon below shows a cartoon of splicing intermediates of the transformer MRNA in male and female flies, where exon 1 is spliced to exon 2 (males) or exon 3 (females). The Sxl protein can bind to the transformer MRNA and prevent exon 1-2 splicing. Where would Sxl be predicted to bind on the transformer pre-mRNA? Transformer pre mANA male splicing female splicing 2 exon 23 solicing Question 2b. The cartoon below shows a gene (with one promoter) that produces a MRNA encoding a 400 amino acid protein. The gene has four exons (boxes) separated by three introns. The bent arrow represents the transcription start site. There are polyadenylation sites (where the newly transcribed MRNA is cleaved and a polyA tail is added) after exons 2, 3 & 4. The initiation codon (ATG) and termination codon (TAA) are indicated in exons 1 and 3 respectively. Assuming that splicing occurs after polyadenylation, list the different RNA products that can be generated from this gene. Which of these MRNAS can produce the 400 amino acid protein? poly A cleavage sites ATG TAA 3 2)
