The correct answer is: D. Cells from different organs may have similar structures.
Explanation:
Every cell in an organism has something in common: its genetic information. Genetic information, in form of DNA, is stored in the nucleus of every cell.
<u>According to the needs of every specific cell, different segments of the DNA are used to synthesize proteins that are useful for that cell.</u> For example, a hepatocyte (cell in the liver) does not have the same proteins as a neuron (nervous cell) because their functions are hugely different, BUT they do share the same genetic information.
