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>
They produce pockets (eggs) for fertilization and they produce the reproductive hormones, oestrogen and progesterone.
