Answer;
-DNA molecule
Explanation;

-The modern version of the Cell Theory includes the ideas that:
-
Energy flow occurs within cells.
- Heredity information (DNA) is passed on from cell to cell.
- All cells have the same basic chemical composition.
-Therefore the study of DNA molecule was instrumental in the formulation of the modern cell theory.
I believe i the correct answer is c because he notices that some of the traits weren't being passed on.
