Scientist discovered that bananas in Gabon are resistant to a virus that destroys banana in Rwanda. Using your knowledge of genetic engineering and gene therapy techniques propose how this resistance could be transferred to Rwandan banana plants to help them resist virus

To transfer virus resistance from Gabonese banana plants to Rwandan banana plants using genetic engineering techniques: Step 1: Identify and Isolate the Resistance Gene. Scientists would first identify the specific gene(s) in the Gabonese banana genome that confer resistance to the virus. This involves comparing the genetic makeup of resistant Gabonese bananas with susceptible Rwandan bananas. Once identified, the gene is isolated using molecular biology techniques. Step 2: Gene Cloning and Vector Preparation. The isolated resistance gene is then cloned (copied multiple times) and inserted into a suitable vector. For plant genetic engineering, a common vector is the Agrobacterium tumefaciens bacterium, which has the natural ability to transfer DNA into plant cells. Step 3: Transformation of Rwandan Banana Cells. Rwandan banana plant cells (often from tissue culture) are then exposed to the Agrobacterium carrying the resistance gene. The bacterium transfers the resistance gene into the genome of the Rwandan banana cells, integrating it into their DNA. Step 4: Regeneration of Whole Plants. The genetically modified banana cells are cultured in a laboratory using plant tissue culture techniques. These cells are induced to regenerate into whole banana plantlets, which now contain the newly introduced resistance gene. Step 5: Selection, Testing, and Propagation. The regenerated plants are screened to confirm the successful integration and expression of the resistance gene. They are then tested for their resistance to the virus. Resistant plants are selected, propagated, and further evaluated in controlled environments and field trials before widespread distribution. Drop the next question.
