These are the five steps in genetic engineering.
- locating and obtaining the DNA of an organism with a particular trait.
- cloning the gene responsible for the phenotype.
- creating a gene with a particular expression pattern.
- transformation, which involves introducing the gene into a crop plant's cells.
- Transgene into a background with affluence.
In the process of genetic engineering, DNA extraction comes first. This is achieved by taking a sample of bacteria that contains the desired gene and subjecting it to a series of procedures that isolate DNA from other components of the cell.
