In general, which one of the following statements is wrong?

Options

A. One codon for one amino acid
B. Many codons can code for one amino acid
C. One codon can code for many amino acids
D. Codons are subject to point mutations

Answer

To determine which statement is wrong regarding codons and amino acids, we will analyze each of the provided statements step by step.

### Step-by-Step Solution:

1. **Understanding Codons**:
- A codon is a sequence of three nucleotides in RNA that corresponds to a specific amino acid.
- Each amino acid is coded by one or more codons, but not the other way around.

2. **Analyzing the Statements**:
- **Statement 1**: "One codon for one amino acid."
- This statement is **correct**. Each codon typically codes for a specific amino acid.

- **Statement 2**: "Many codons can code for one amino acid."
- This statement is also **correct**. For example, the amino acid isoleucine can be coded by three different codons: AUA, AUU, and AUC.

- **Statement 3**: "One codon can code for many amino acids."
- This statement is **incorrect**. Each codon is specific to one amino acid, meaning that one codon cannot code for multiple amino acids.

- **Statement 4**: "Codons are subjected to point mutation."
- This statement is **correct**. Mutations can occur in the DNA sequence, which may change one nucleotide in a codon, potentially altering the amino acid that is coded.

3. **Conclusion**:
- The wrong statement among the four provided is **Statement 3**: "One codon can code for many amino acids."

### Final Answer:
The wrong statement is: **"One codon can code for many amino acids."**
