Question:

Which technique of genetic engineering allows us to introduce only desirable genes into a target organism?

 

Options:

Gene sequencing

Hybridization

Gene cloning and transfer

Polymerase Chain Reaction (PCR)

Correct Answer:

Gene cloning and transfer

Explanation:

c) Gene cloning and transfer

Explanation: Gene cloning and transfer are techniques used in genetic engineering that allow scientists to introduce only desirable genes into a target organism. In gene cloning, specific genes of interest are isolated and inserted into DNA molecules known as vectors. These vectors can then be transferred into the target organism, where the desirable genes are integrated into the organism's genome. This process enables the target organism to express the desired traits encoded by the introduced genes, without introducing unwanted or undesirable genes. Gene cloning and transfer are essential tools in genetic engineering, enabling the creation of genetically modified organisms with specific, beneficial traits.

Gene sequencing, hybridization, and PCR are all valuable techniques in genetic engineering, but they do not allow us to introduce only desirable genes into a target organism. Gene sequencing is used to determine the order of the nucleotides in a gene. Hybridization is used to identify complementary DNA sequences. PCR is used to amplify DNA sequences
