The base sequence of nucleic acid is ACG, GGA, CGA, CCA from this it can be inferred that it is a segment of -

Options

A. DNA
B. m-RNA
C. t-RNA
D. Data-insufficient

Answer

To solve the question regarding the base sequence of nucleic acid ACG, GGA, CGA, CCA, we need to analyze the components of the nucleic acid and determine whether it is DNA, mRNA, tRNA, or if the data is insufficient.

### Step-by-Step Solution:

1. **Identify the Base Sequence**: The given base sequence is ACG, GGA, CGA, CCA.

2. **Understand the Components of DNA and RNA**:
- **DNA** contains four nitrogenous bases: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C).
- **RNA** contains four nitrogenous bases: Adenine (A), Uracil (U), Guanine (G), and Cytosine (C).

3. **Analyze the Given Sequence**:
- The sequence provided (ACG, GGA, CGA, CCA) does not contain Thymine (T) or Uracil (U).
- The absence of Thymine suggests that it cannot be DNA, as DNA must have Thymine.

4. **Determine the Type of RNA**:
- Since the sequence does not contain Uracil either, it cannot be classified as mRNA or tRNA, as both types of RNA must contain Uracil.

5. **Conclusion**: Since the sequence lacks both Thymine and Uracil, we cannot definitively classify it as DNA or RNA. Therefore, the data is insufficient to determine the type of nucleic acid.

### Final Answer:
The correct inference is that the data is insufficient.
