Choose the correct pair having same meaning

Options

A. DNA fingerprinting-DNA frofiling
B. Gene pool-genome
C. Codon-gene
D. Cistron-triplet

Answer

To solve the question "Choose the correct pair having the same meaning," we need to analyze each pair of terms provided in the options and determine if they refer to the same concept.

### Step-by-Step Solution:

1. **Identify the Options**: The options provided are:
- A) DNA fingerprinting = DNA profiling
- B) Gene pool = Genome
- C) Codon = Gene
- D) Cistron = Triplet

2. **Analyze Option A**:
- **DNA Fingerprinting**: This is a technique used to identify individuals based on their unique DNA patterns. It is commonly used in forensic science and paternity testing.
- **DNA Profiling**: This is essentially the same as DNA fingerprinting; it involves analyzing the DNA to create a profile for identification purposes.
- **Conclusion**: Both terms refer to the same technique, so this pair is correct.

3. **Analyze Option B**:
- **Gene Pool**: This refers to the total collection of genes in a population at a given time.
- **Genome**: This is the complete set of genes or genetic material present in a cell or organism, typically referring to a single organism's haploid set of chromosomes.
- **Conclusion**: These terms are not synonymous; therefore, this pair is incorrect.

4. **Analyze Option C**:
- **Codon**: This is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid or stop signal during protein synthesis.
- **Gene**: This is a segment of DNA that contains the instructions for building a protein or RNA molecule.
- **Conclusion**: These terms refer to different concepts; thus, this pair is incorrect.

5. **Analyze Option D**:
- **Cistron**: This is a term used to describe a segment of DNA that encodes a single polypeptide (protein).
- **Triplet**: This refers to the three-nucleotide sequence in mRNA that codes for an amino acid (also known as a codon).
- **Conclusion**: While related, these terms are not the same; hence, this pair is incorrect.

6. **Final Conclusion**: The only correct pair that has the same meaning is:
- **A) DNA fingerprinting = DNA profiling**

### Final Answer:
The correct answer is **Option A: DNA fingerprinting = DNA profiling**.
