DNA
It's called the specific gravity of a material, and it is the weight of a specific volume of material, compared to an equal volume of water, expressed as a number. Galena, for instance, has a specific gravity of 7.4, indicating that it is 7.4 times heavier than water.
Proteins are constructed in cells according to the instructions coded into DNA. Proteins are also much easier to see than the coding of DNA molecules, so there was a time where differences between proteins were detectable and differences in DNA were not detectable. As such, the logical hypothesis is that proteins are inherited and duplicated without any other source of instructions. In fact, it is DNA that is hereditary, and the variations in proteins that were observed to be hereditary previously are now understood to be artefacts from the use of the same DNA instructions.
