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.
What else can I help you with?
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.
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.
Who first isolated DNA from white blood cells?
Adam Walley Ph. D Harvard University Advanced Sociology Professor
Did the Swiss chemist Friedrich Miescher isolated DNA from fish sperm and the pus of open wounds?
Yes, Friedrich Miescher isolated a substance from the nuclei of white blood cells found in pus, which he initially called "nuclein." Later research has confirmed that this substance is DNA. Miescher did not isolate DNA from fish sperm specifically, but his work laid the foundation for the discovery of DNA as the genetic material 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 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 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.

What is Johann Miescher credited with?
Johann Miescher is credited with the discovery of nucleic acids, specifically DNA, in 1869. While studying white blood cells, he isolated a substance he called "nuclein," which was later identified as DNA. His work laid the foundation for future research into genetics and molecular biology, highlighting the importance of nucleic acids in heredity and cellular function.
How is plasmid DNA inserted into the cell where the DNA originally come from?
by transformation
How was DNA discovered by miescher in 1869?
In 1869, Swiss chemist Friedrich Miescher discovered DNA while studying white blood cells. He isolated a substance he called "nuclein" from the nuclei of these cells, which contained high amounts of phosphorus and was distinct from proteins. Miescher's work laid the foundation for understanding DNA as the carrier of genetic information, although its role was not fully recognized until later discoveries in molecular biology.
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 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.
