If UUU codes for phenylalanine in most of the organisms then it shows that

Options

A. Code is nearly universal
B. Code is degenerate
C. Code is ambiguous
D. All organisms share same genetic informations

Answer

To solve the question "If UUU codes for phenylalanine in most of the organisms then it shows that," we can analyze the options provided based on the characteristics of the genetic code.

### Step-by-Step Solution:

1. **Understanding Codons**: A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid. In this case, UUU is the codon that codes for the amino acid phenylalanine.

2. **Universal Code**: The fact that UUU codes for phenylalanine in most organisms suggests that the genetic code is nearly universal. This means that the same codons specify the same amino acids across a wide range of organisms, indicating a common evolutionary origin.

3. **Degenerate Code**: The genetic code is described as degenerate because most amino acids are encoded by more than one codon. However, in this case, we are specifically looking at the codon UUU, which uniquely codes for phenylalanine. Therefore, this option does not apply here.

4. **Ambiguous Code**: An ambiguous code would imply that a single codon could code for more than one amino acid. This is not the case for UUU, as it specifically codes for phenylalanine. Thus, this option is also incorrect.

5. **Shared Genetic Information**: While many organisms share similar genetic codes, there can be variations in the genetic information. Therefore, stating that all organisms share the same genetic information is not accurate.

6. **Conclusion**: The correct interpretation of the statement is that the genetic code is nearly universal since UUU codes for phenylalanine in most organisms.

### Final Answer:
The correct choice is that the genetic code is nearly universal.
