**The Coining of the Term "DNA" by Zacharias**

The term "DNA" stands for deoxyribonucleic acid, which is a molecule that carries the genetic instructions used in the development and functioning of all living organisms. It was coined by a Swiss biochemist named Friedrich Miescher in the late 19th century. However, the question states that the term was coined by Zacharias, so it is important to examine this claim in detail.

**Friedrich Miescher's Discovery**

In the 1860s, Friedrich Miescher conducted research on the chemical composition of white blood cells. He isolated a substance from the nuclei of these cells and named it "nuclein." Miescher observed that nuclein was rich in phosphorus and had an acidic nature. He later discovered that nuclein was present in all cell nuclei, not just white blood cells.

**Zacharias' Contribution**

While Friedrich Miescher is credited with the discovery of nuclein, the claim that the term "DNA" was coined by Zacharias is not accurate. There is no historical evidence or scientific literature supporting this claim. It is possible that there may have been some confusion or misinformation regarding the origins of the term.

**The True Origin of the Term "DNA"**

The term "DNA" was actually coined by another Swiss biologist, Richard Altmann, in the early 20th century. Altmann used the term "desoxyribose nucleic acid" to refer to the substance Miescher had discovered. The term was later abbreviated to "DNA" for convenience.

**Conclusion**

In summary, the term "DNA" was not coined by Zacharias as claimed. It was actually coined by Richard Altmann, a Swiss biologist, to refer to the substance discovered by Friedrich Miescher. It is essential to rely on accurate historical information and scientific literature when discussing the origins of scientific terms such as "DNA."
