Who first identified nucleic acids, and where were they discovered? Friedrich Meischer discovered nucleic acids in blood cells. Phoebus Levine discovered nucleic acids in plant cells. James Watson and Francis Crick discovered nucleic acids in DNA. Gerardus Johannes Mulder discovered nucleic acids in bacterial cells.

Friedrich Meischer discovered nucleic acids in blood cells.

Explanation:

Nucleic acid is one of the four biological molecules. It is a polymer made up of monomeric units called Nucleotides. Nucleic acids make up two important molecules namely: DNA and RNA.

Nucleic acid was first discovered in the 1860's by a then young Swiss scientist called Friedrich Miescher. He was working on white blood cells and discovered a new compound that was different from the already known biomolecules i.e. carbohydrates, proteins, and lipids etc. This compound isolated by Friedrich Miescher was then called "NUCLEIN" because he got it from the nuclei of a blood cell.

His discovery was later proven to be Deoxyribose nucleic acid (DNA), the genetic material.

emerald ash borer

the emerald ash borer is a green buprestid or jewel beetle native to north-eastern asia that feeds on ash species. females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years. hope this !
