The prokaryotic structure credited for transfer of gene from one organism to another organism is

Options

A. Ribosome
B. Mitochondria
C. Plasmid
D. Polysome

Answer

To answer the question about the prokaryotic structure credited for the transfer of genes from one organism to another, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for a prokaryotic structure involved in gene transfer. This indicates we are looking for a component found in prokaryotic cells (like bacteria).

2. **Evaluate the Options**: The options provided are Ribosome, Mitochondria, Plasmids, and Polysome. We need to analyze each option to determine which one is involved in gene transfer.

3. **Analyze Ribosome**: Ribosomes are cellular structures responsible for protein synthesis. They do not play a role in the transfer of genes between organisms. Therefore, we can eliminate this option.

4. **Analyze Mitochondria**: Mitochondria are double-membraned organelles found in eukaryotic cells, not prokaryotic cells. Since the question specifically refers to prokaryotic structures, this option can also be eliminated.

5. **Analyze Polysome**: Polysomes are clusters of ribosomes translating mRNA simultaneously. Like ribosomes, they are not involved in gene transfer, so this option is also eliminated.

6. **Analyze Plasmids**: Plasmids are small, circular, double-stranded DNA molecules found in prokaryotic cells. They are extra-chromosomal and can replicate independently of chromosomal DNA. Plasmids can carry genes that confer advantageous traits, such as antibiotic resistance, and can be transferred between bacteria through processes like conjugation.

7. **Conclusion**: Based on the analysis, the prokaryotic structure credited for the transfer of genes from one organism to another is **Plasmids**.

### Final Answer:
The prokaryotic structure credited for the transfer of genes from one organism to another organism is **Plasmids**.
