The rebound hypertension that is seen when beta-adrenergic antagonists such as propranolol (Inderal) are discontinued abruptly is most probably due to which of the following 

  You have discovered a gene (Figure 7-3A) that is alternatively spliced to produce several forms of mRNA in various cell types, three of which are shown in Figure 7-3B. The lines connecting the exons that are included in the mRNA indicate the splicing. From your experiments, you know that protein translation begins in exon 1. For all forms of the mRNA, the encoded protein sequence is the same in the regions of the mRNA that correspond to exons 1 and 10. Exons 2 and 3 are alternative exons used in different mRNA, as are exons 7 and 8. Which of the following statements about exons 2 and 3 is the most accurate?   Figure 7-3
