Answer:
The proteins are expressed differently in each cell.
Explanation:
<u>The correct answer would be that the proteins are expressed differently in each cell. </u>
The regulation of gene expression is primarily responsible for differential functions of the same DNA sequence. Multiple proteins are formed from the same DNA sequence but only the required ones are specifically expressed depending on the cell.
<em>In other words, in the blood cells, the protein is expressed for performing blood-specific functions while it is expressed for performing skin-specific functions in the skin.</em>
Normal proteins allow the substances Na + and Cl- to move correctly through the cells of the skin, the pancreas and the lungs.
In contrast, the mutated proteins prevent them from moving through the cell, this causes mucus to accumulate in the skin, in the lungs and the pancreas, a medical condition called cystic fibrosis.
