Pit vipers are snakes that have deep sensory openings (pits) between their nostrils and eyes. These pits enable the snakes to sense heat emitted by endotherms, such as mammals, allowing the snakes to find their prey. In an experiment, researchers discovered that nerve cells in the pits transcribe the gene ???? ???? ???? ???? 1 400 times more often than do other nerve cells in the snakes. The researchers claim that the ???? ???? ???? ???? 1 gene is involved in the snakes’ ability to sense heat. Which of the following would be the best control to add to the researchers’ experiment? Measuring translation of TRPA1 mRNA in pit nerve cells Option A,Measuring translation of T R P A 1 m R N A in pit nerve cells Measuring translation of TRPA1 mRNA in nerve cells of mammals Option B,Measuring translation of T R P A 1 m R N A in nerve cells of mammals Measuring ???? ???? ???? ???? 1 transcription in nerve cells of snakes lacking pits Option C,Measuring T
