Which out of the following statement is incorrect ?

Options

A. Genetic code is ambiguous
B. Genetic code is degenerate
C. Genetic code is universal
D. Genetic code is non-overlapping

Answer

To solve the question of identifying the incorrect statement about the genetic code, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Genetic Code**: The genetic code consists of codons, which are sequences of three nucleotides that correspond to specific amino acids in protein synthesis.

2. **Evaluate the First Statement**: The first statement claims that "genetic code is ambiguous." This is incorrect because the genetic code is actually unambiguous. Each codon corresponds to only one amino acid.

3. **Evaluate the Second Statement**: The second statement claims that "the genetic code is degenerate." This is correct. Degeneracy means that multiple codons can code for the same amino acid, but each codon only codes for one specific amino acid.

4. **Evaluate the Third Statement**: The third statement claims that "the genetic code is universal." This is also correct. The same codons code for the same amino acids across different organisms, from bacteria to humans.

5. **Evaluate the Fourth Statement**: The fourth statement claims that "the genetic code is overlapping." This is incorrect. The genetic code is non-overlapping, meaning that each nucleotide is part of only one codon and does not overlap with adjacent codons.

6. **Conclusion**: After evaluating all statements, we find that the first statement is incorrect. Therefore, the answer to the question is that the first statement is the only incorrect one.

### Final Answer:
The incorrect statement is: "Genetic code is ambiguous."
