Scientists use plasmids as important tools for making genetically modified organisms, or GMOs.
But what are plasmids?
Plasmids are small, circular pieces of DNA found in bacteria. They can copy themselves separately from the main DNA, which makes them great for moving genes from one organism to another.
Here’s a simple breakdown of how this process works:
Finding the Target Gene: First, scientists locate the specific gene they want to add to another organism. They use special enzymes to cut the DNA at specific points.
Inserting the Gene into the Plasmid: Once they have the target gene, scientists put it into the plasmid using the same enzymes. This modified plasmid is called recombinant DNA.
Transformation: The next step is introducing the recombinant plasmid into a host organism, like a bacterial cell. This step is called transformation. It allows the host cell to take in the new gene.
Selection and Observation: Scientists look for certain markers, like antibiotic resistance, to find which organisms have been successfully modified. Only those with the plasmid will survive when exposed to the antibiotic.
Growth and Study: When they confirm the changes, these modified organisms can be grown and studied. They will produce specific proteins or traits that can be useful in farming, medicine, and research.
In short, plasmids are like helpful vehicles for genetic engineering. They make it possible to mix genes between different types of organisms and improve their traits to create GMOs.
