One codon codes for only one amino acid, hence the code is

Options

A. Ambiguous and non-specific
B. Unambiguous and specific
C. Ambiguous and specific
D. Unambiguous and non-specific

Answer

To solve the question "One codon codes for only one amino acid, hence the code is", we need to analyze the characteristics of the genetic code. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Genetic Code
The genetic code is a set of rules that defines how the information encoded in genetic material (DNA or mRNA sequences) is translated into proteins (amino acid sequences).

**Hint:** The genetic code relates nucleotides in DNA/mRNA to amino acids in proteins.

### Step 2: Define a Codon
A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid or a stop signal during protein synthesis.

**Hint:** Remember that codons are made up of three nucleotides.

### Step 3: Analyze the Statement
The statement "One codon codes for only one amino acid" indicates that each specific codon corresponds uniquely to a single amino acid.

**Hint:** Think about the implications of a codon being unique to one amino acid.

### Step 4: Identify Key Terms
The terms "unambiguous" and "specific" are crucial. "Unambiguous" means that each codon specifies one and only one amino acid, while "specific" indicates that the codon is precise in its coding.

**Hint:** Consider what "unambiguous" means in the context of genetic coding.

### Step 5: Evaluate the Options
- **Ambiguous and Non-specific**: Incorrect, as it does not fit the definition.
- **Unambiguous and Specific**: Correct, as it matches the statement.
- **Ambiguous and Specific**: Incorrect, as "ambiguous" contradicts the uniqueness of the codon.
- **Unambiguous and Non-specific**: Incorrect, as "non-specific" contradicts the precision.

**Hint:** Cross-reference the definitions of the terms with the options provided.

### Step 6: Conclusion
Based on the analysis, the correct answer is "Unambiguous and Specific" because one codon indeed codes for only one specific amino acid.

**Final Answer:** The code is "Unambiguous and Specific".
