Nucleic acids were first demonstrated in_________________?
Correct answer: A. Pus cells
- A. Pus cells
- B. Sperm heads
- C. 1872
- D. all of the above
Explanation
Friedrich Miescher first isolated and demonstrated nucleic material, called nuclein, from the nuclei of pus cells. Sperm heads were studied later, while 1872 is a year rather than a biological material, so choosing “all of the above” incorrectly treats every option as a valid answer to the same question.

About Classification of Organic Compounds
Organic compounds are classified by carbon skeleton into open-chain, branched-chain and cyclic compounds, including homocyclic and heterocyclic types. The classification also uses functional groups to distinguish hydrocarbons, halo compounds, alcohols, aldehydes, ketones, carboxylic acids and their derivatives, which is different from naming compounds by IUPAC rules.
