Who first discovered nuclein?
Friedrich Miescher, a Swiss biochemist, first discovered nuclein in 1869. He isolated a substance now known as DNA from the nuclei of white blood cells.
Why was DNA originally called nuclein?
DNA was originally called nuclein because it was first isolated from the nuclei of white blood cells by Friedrich Miescher in 1869. At that time, its exact function and significance were not understood, so it was named based on its location of discovery within the cell.
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"
Who discovered RNA?
Friedrich Miescher is credited with the discovery of RNA in 1869. He isolated a new type of nucleic acid from the nuclei of cells, which he called "nuclein." It was later identified to be RNA.
How nucleic was discovered?
Nucleic acids were discovered by Friedrich Miescher in 1869. He isolated a substance from the nuclei of cells that contained high amounts of phosphorus, which he called nuclein. Later, this substance was found to be composed of nucleic acids, which carry genetic information in cells.
What types of cells did Friedrich Miescher work with?
Friedrich Miescher worked with white blood cells obtained from pus collected from surgical bandages. He isolated and identified a new substance which he called nuclein, later known as DNA.
When did Frederick Miescher discover DNA?
Frederick Miescher discovered DNA in 1869 while studying the nucleus of white blood cells. He isolated a new chemical substance from cell nuclei that he called "nuclein," which we now know as DNA.
What two things credited with discovering structure of DNA?
James Watson and Francis Crick are credited with discovering the double helix structure of DNA in 1953. Their model provided a groundbreaking explanation of how genetic information is stored and transmitted in living organisms.

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.
Who first isolated DNA from white blood cells?
Friedrich Miescher, a Swiss scientist, first isolated DNA from white blood cells in 1869. He called this substance "nuclein" and later it became known as DNA.
