Scenаriо 1 – “Muscle‑Twitch Mice” (10 Pоints) A cоlony of lаb mice hаs begun displaying sudden, short bursts of running whenever a loud sound occurs. Researchers discover a dominant allele T that encodes a hyperactive epinephrine receptor in skeletal‑muscle cells.   Which change most directly explains the mice’s behavior? [1] Hyper‑activity of this receptor would first increase the activity of which enzyme inside the muscle cell? [2] To verify that the T allele produces a longer receptor protein, what step follows transcription of the T mRNA?[3] If skeletal‑muscle cells alone express the epinephrine‑receptor gene, which explanation is most consistent? [4] Researchers design primers flanking a 180 bp region that includes the T mutation. After PCR and agarose‑gel analysis they expect the mutant allele to show: [5]
