Nuclein is an early term used to describe what we now know as nucleic acids, specifically DNA and RNA. It was first identified by Friedrich Miescher in the late 19th century while he was studying cell nuclei. Nuclein refers to the acidic substance containing genetic information that plays a crucial role in heredity and cellular functions. Today, the term has largely fallen out of use, with "DNA" and "RNA" being the preferred terminology.

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 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.


Who isolated a previously unknown molecule from the nuclei of cells called this molecule nuclein?

The molecule known as "nuclein" was isolated by Friedrich Miescher in 1869. He extracted it from the nuclei of white blood cells, identifying it as a distinct substance that contained both protein and an acidic component. This groundbreaking discovery laid the foundation for the later understanding of DNA and its role in heredity.

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 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.


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 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!
