These findings led to the formation of the modern cell theory, which has three main additions: first, that DNA is passed between cells during cell division; second, that the cells of all organisms within a similar species are mostly the same, both structurally and chemically; and finally, that energy flow occurs within . Among Louis Pasteur's discoveries were molecular asymmetry, the fact that molecules can have the same chemical composition with different structures; that fermentation is caused by microorganisms; and that virulence can be increased as well as decreased.
