Gene tranfer between unrelated organisms i.e., (i.e., prokaryote and eukaryote) is possible by

Options

A. r-DNA technology
B. Hybridization
C. Polyploid breeding
D. Mutation breeding

Answer

**Step-by-Step Solution:**

1. **Understanding Gene Transfer**: Gene transfer between unrelated organisms, including prokaryotes (like bacteria) and eukaryotes (like plants and animals), is a significant concept in genetics. This transfer allows for the introduction of new traits and characteristics into different species.

2. **Identifying the Mechanisms**: There are several mechanisms through which gene transfer can occur:
- **Recombinant DNA (rDNA) Technology**: This is a method that involves combining DNA from different organisms. It allows for the insertion of genes from one organism into another, regardless of their taxonomic relationship.
- **Hybridization**: This refers to the process of combining different varieties or species to produce hybrids. However, it typically occurs within closely related organisms.
- **Polyploid Breeding**: This involves organisms that have more than two sets of chromosomes. It is usually relevant in plant breeding and does not apply to gene transfer between unrelated organisms.
- **Mutation Breeding**: This involves inducing mutations to create variability within a species. It does not facilitate gene transfer between different species.

3. **Conclusion**: Among the options provided, the most appropriate method for gene transfer between unrelated organisms (prokaryotes and eukaryotes) is **Recombinant DNA (rDNA) Technology**. This technology enables the direct manipulation of genetic material and is widely used in biotechnology.

4. **Final Answer**: The correct answer is **Recombinant DNA (rDNA) Technology**.
