Why was DNA originally called nuclein?
DNA actually stands for "DeOxyRibo Nucleic Acid", which is an actual chemical name. It was originally called "Nuclein" because the chemical structure was unknown. All that was known was that, whatever it was, it was contained within the nucleus of white blood cells. Therefore, it was named, "nuclein" by Friedrich Miescher in circa 1869-1871.
Where did he get nuclein from?
he added some simple demicalj to the missrocope cells islated awinite percipitate.
What impact did Frederick Miescher discovering DNA have on the scientific world?
Frederick Miescher was responsible for discovery nuclein (later known as DNA) so bascially he started the search for what DNA was which led to discovering hereditary information and the secrets of life. So yes, a pretty important discovery!
When does DNA discovered?
DNA was first isolated by the Swiss physician Friedrich Miescher who, in 1869, discovered a microscopic substance in the pus of discarded surgical bandages. As it resided in the nuclei of cells, he called it "nuclein"
DNA was found by who?
A German Chemist, Friedrich Miescher, discovered DNA in 1869, only four years after Mendel's work was published. Miescher extracted a white substance from the nuclei of human cells and fish sperm. he called this substance "nuclein" because it seemed to be specifically associated with the nucleus.
What two things credited with discovering structure of DNA?
In 1869, the physician Friedrich Miescher first isolated DNA. While examining the substance ofpus in surgical bandages, he observed a microscopic substance in the pus. He named it nuclein because he observed it in the nuclei of cells. Then, in 1919, Phoebus Levene realized that this "nuclein" was composed of a base, a sugar, and a phosphate nucleotide unit. Attempting to discern the structure of the DNA, Levene proposed that it was structured out of a string of nucleotides units that were linked together. He suggested that they were linked together through the phosphate groups. This conjecture was wrong however, because Levene's suggested a short chain. He further suggested that the bases repeated in a fixed order, which was incorrect.

What did friedrich miescher contribution to DNA story?
Swiss physician Friedrich Miescher in 1869, while studying proteins in the leucocytes, isolated DNA and found it quite different from other proteins. Since it was present in the nucleus, he termed this substance as nuclein.
