What did Friedrich Miescher contribute to the study of DNA?

Who named Nuclein?

Miescher recognised that he had discovered a novel molecule. Since he had isolated it from the cells’ nuclei he named it nuclein, a name preserved in today’s designation deoxyribonucleic acid.

Which important property did Friedrich Miescher discover?

Answer: Friedrich Miescher first discovered DNA as a biomolecule. He isolated nuclein in which DNA is wrapped around cellular proteins such as Histones. Many years after Miescher’s discovery it was proved that DNA is the hereditary material in cells.
