The best answer is D. He extracted and observed DNA from white blood cells. He is a Swiss physician and a biologist who is known to be the first researcher to identify nucleic acid. He isolated various phosphate-rich chemicals , which he called nuclein or what we know now as nucleic acid, from white blood cells' nuclei which paved the way for him to discover and identify DNA.

Answer from: jesseemartinez22

Friedrich Miescher (D) extracted DNA from white blood cells.

Further Explanation:

A geneticcode is the rules employed by the cell to translate info that are encoded in deoxyribonucleic acid or ribonucleic acid into protein. DNA or deoxyribonucleic acid is the hereditary material in humans and most the other living organisms. While ribonucleic acid or RNA is formed once deoxyribonucleic acid undergoes transcription. It contains the codes that are needed for protein synthesis (translation). The deoxyribonucleic acid and ribonucleic acid differ from one another in varied aspects like strand (DNA- double stranded, RNA- single stranded usually) Base pairs (DNA-ATGC; RNA-AUGC), Types, (DNA- A, B, Z type; RNA- RNA, rRNA, tRNA etc.). Friedrich Miescher isolated "nuclein" that is DNA along with related proteins from the cell nuclei in 1869. DNA as a definite molecule was 1st known by Friedrich Miescher. White blood cells usually abbreviated as WBC additionally called leukocytes are those cells that defend the body from contagious diseases additionally as foreign invaders that are observed as antigens. Thus, the right choice to this question is D that says that the contribution of Friedrich Miescher is that he extracted and discovered DNA from the white blood cells.
