So pepsin would not break it down: it would most probably not react with glucose at all, since pepsin breaks down proteins, not carbohydrates. <span />
Answer:
The mouse CFTR gene and human CFTR gene encode proteins that can serve a similar function.
Explanation:
CFTR (Cystic fibrosis transmembrane conductance regulator) gene that codes for the membrane protein. This gene is responsible for the transport of the chloride ions in the cell.
Any mutation in CFTR gene can cause the lung diseases in individual. As shown in the experiment the mouse gets normal when given normal human CFTR gene. The CFTR gene plays the similar role and function in both huamn and mouse.
Thus, the correct answer is option (C).
