Which one of the following pairs of terms/names mean one and the same thing

Options

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

Answer

To solve the question of which pair of terms means one and the same thing, we will analyze each option step by step.

### Step 1: Analyze the first pair - Gene Pool and Genome
- **Gene Pool**: This refers to the total genes present in a population, encompassing all genetic variations within that population.
- **Genome**: This is the complete set of genetic material (DNA) of an organism, including all of its genes.

**Conclusion**: Gene pool and genome are not the same.

### Step 2: Analyze the second pair - Codon and Gene
- **Codon**: A codon is a sequence of three nucleotides in DNA or RNA that specifies an amino acid.
- **Gene**: A gene is a segment of DNA that contains the instructions for making a protein, which can consist of many codons.

**Conclusion**: Codon and gene are not the same.

### Step 3: Analyze the third pair - Cistron and Triplet
- **Cistron**: A cistron is a segment of DNA that codes for a polypeptide chain, essentially synonymous with a gene.
- **Triplet**: A triplet refers to a sequence of three nucleotides that codes for a specific amino acid.

**Conclusion**: Cistron and triplet are related but not the same.

### Step 4: Analyze the fourth pair - DNA Fingerprinting and DNA Profiling
- **DNA Fingerprinting**: This technique identifies and evaluates the genetic information of an individual, based on the uniqueness of their DNA.
- **DNA Profiling**: This process also involves analyzing an individual's DNA to determine their genetic characteristics, often used for identification purposes.

**Conclusion**: DNA fingerprinting and DNA profiling are essentially the same, as both evaluate genetic information for identification.

### Final Answer
The pair of terms that mean one and the same thing is **DNA Fingerprinting and DNA Profiling**.
