Final answer:

Friedrich Miescher's discovery of nuclein from white blood cells in the 1860s laid the groundwork for understanding RNA and DNA, contributing to the discovery of the genetic code.


Explanation:

Friedrich Miescher's contribution to the discovery of the genetic code was his isolation of phosphate-rich chemicals from white blood cells in the 1860s. He named these chemicals 'nuclein' because they were isolated from the nuclei of the cells, which eventually led to the understanding of RNA and DNA.
