How does the recombinant DNA technology overcomes the limitation of traditional hybridization i.e, inclusion and multiplication of undesirable genes along with the desired genes? |
By using gene cloning only By using gene transfer only Both I and II None of these |
Both I and II |
a-By using gene cloning only b-By using gene transfer only c-Both I and II is the correct option d-None of these Traditional hybridization procedures involve crossing two parent organisms with desirable traits to create offspring with a combination of these traits. However, this process is not very precise, and it may result in the inclusion and multiplication of undesirable genes along with the desired genes in the offspring. This is because the genes from both parent organisms are inherited, and there is no control over which specific genes will be passed on to the offspring. In contrast, genetic engineering techniques, such as creating recombinant DNA, gene cloning, and gene transfer, provide a more precise and controlled way to introduce desirable genes into an organism without introducing undesirable genes. Here's how each technique works:
Using these genetic engineering techniques, scientists can introduce only the desired genes into the target organism, thereby overcoming the limitations of traditional hybridization methods. This precision and control are crucial in modern biotechnology and have enabled the development of genetically modified organisms (GMOs) with specific traits that benefit agriculture, medicine, and various other fields. |
