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.


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.


True or false Despite years of research the actual structure of the DNA molecule is still unknown?

False. The structure of the DNA molecule was discovered by James Watson and Francis Crick in 1953. They proposed the double helix structure that is now widely accepted.
