Question:
Who discovered DNA?
Who discovered DNA?
Show Hint
Remember that Miescher discovered DNA, but its role as the genetic material was established later by experiments like those of Avery, MacLeod, and McCarty.
Updated On: Apr 15, 2025
- Watson and Crick
- F. Miescher
- Rosalind Franklin
- Griffith
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Friedrich Miescher discovered DNA in 1869, isolating "nuclein" from pus cell nuclei.
Key points:
- Watson and Crick: Discovered DNA's double-helix structure.
- Rosalind Franklin: Contributed to structural discovery via X-ray diffraction.
- Griffith: Demonstrated DNA as genetic material through transformation experiments.
Therefore, Friedrich Miescher is credited with the initial discovery of DNA.
