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.

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.
When Marie curie isolated uranium from pitchblende realized that the pitchblende was more radioactive than the uranium she had extracted what did she conclude about her observations?
Marie Curie concluded that pitchblende contained other radioactive elements in addition to uranium, as its radioactivity exceeded that of the uranium she had isolated. This led her to hypothesize the presence of previously unknown radioactive substances. Her observations ultimately resulted in the discovery of polonium and radium, further advancing the understanding of radioactivity and its elements.
Is discoveries an adjective?
No it is not. Discoveries is a plural noun.
What does disdosure mean?
Disclosure is the act of sharing information or making something known to others. It typically involves revealing details that were previously unknown or hidden.
If an unknown molecule turned light blue with Benedict's solution violet with Biuret solution and yellow with IKI what type of biological molecule would this be?
The unknown molecule is likely a protein, as indicated by the violet reaction with Biuret solution, which tests for the presence of peptide bonds. The light blue color with Benedict's solution suggests the presence of reducing sugars, but the yellow color with IKI (iodine solution) indicates the presence of starch or other polysaccharides. Therefore, the molecule may be a complex mixture containing proteins and carbohydrates, possibly indicating a glycoprotein or a similar compound.
