Genetic code is same in all living organisms hence it is called

Options

A. Colinear
B. Universal
C. Unambiguous
D. Commaless

Answer

### Step-by-Step Solution

1. **Understanding Genetic Code**: The genetic code refers to the set of rules that dictate how the information encoded in DNA is translated into proteins. It consists of codons, which are sequences of three nucleotides that correspond to specific amino acids.

2. **Universality of Genetic Code**: The question states that the genetic code is the same in all living organisms. This means that regardless of the organism—be it a bacterium, plant, or animal—the same codons will code for the same amino acids. This characteristic of the genetic code is referred to as "universality."

3. **Evaluating Options**: The question provides several options to choose from:
- Co-linear
- Universal
- Unambiguous
- Commas

4. **Analyzing Each Option**:
- **Co-linear**: This term refers to the direct correspondence between the sequence of nucleotides in DNA and the sequence of amino acids in proteins. While it is a valid concept, it does not describe the universality of the genetic code.
- **Universal**: This is the correct option, as it accurately describes the fact that the genetic code is the same across all living organisms, with minor exceptions.
- **Unambiguous**: This term means that each codon specifies only one amino acid. While true, it does not address the universality aspect.
- **Commas**: This term refers to the continuous and non-overlapping nature of the genetic code, but again, it does not relate to the universality of the code.

5. **Conclusion**: After evaluating all options, the correct answer is "Universal," as it encapsulates the idea that the genetic code is the same in all living organisms.

### Final Answer
The genetic code is same in all living organisms; hence it is called **Universal**.
