The term triplet genetic code were coined by

Options

A. Watson and Crick
B. Nirenberg
C. Gamow
D. Conrat

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks who coined the term "triplet genetic code." This requires knowledge of the history of genetic research and the contributions of various scientists.

2. **Defining Genetic Code**: The genetic code consists of sequences of nucleotides in DNA or RNA that correspond to specific amino acids. A triplet codon is a sequence of three nucleotides that codes for one amino acid.

3. **Identifying Key Scientists**: The question provides several names: Watson and Crick, Nirenberg, Gamow, and Conrad. We need to evaluate their contributions to determine who coined the term.

4. **Analyzing Contributions**:
- **Watson and Crick**: They are known for discovering the double-helix structure of DNA, not for the genetic code itself.
- **Nirenberg**: He contributed to deciphering the genetic code and demonstrated that codons are triplets, but he did not coin the term.
- **Gamow**: He is credited with coining the term "triplet genetic code." He proposed that the genetic code is made up of triplets of nucleotides.
- **Conrad**: There is no significant contribution related to the triplet genetic code attributed to him.

5. **Conclusion**: Based on the analysis, the correct answer to the question is George Gamow, as he coined the term "triplet genetic code."

**Final Answer**: The term "triplet genetic code" was coined by George Gamow.
