Introduction to Recombinant DNA Technology
Recombinant DNA technology is a big leap in biotechnology. It lets us change an organism’s genes to add new traits. This started in the 1970s with the discovery of restriction enzymes.
Now, it’s key in medicine, agriculture, and food making. It’s all about changing genes in living things.
There are three main ways to do this: transformation, non-bacterial transformation, and phage introduction. These methods use plasmids or bacteriophages to add new genes. This is how we make things like human insulin.
Genetic engineering is not just for medicine. It’s also used in farming. For example, Flavr Savr tomatoes and Golden Rice are genetically modified. They grow better and fight pests.
It also helps in making food better and last longer. This shows how wide its impact is.
In medicine, genetic engineering is crucial. It helps in gene therapy and making proteins like Factor VIII. These are used to treat diseases like hemophilia A.
The success of these treatments depends on advanced tools. These tools help us understand and work with DNA. This technology keeps pushing the boundaries of what’s possible.
