Genetic Manipulation

Leave a Comment / MPYE-013 Philosophy of Technology /

Genetic Manipulation Genetic Manipulation is the process of altering the DNA of an organism to achieve desired traits. This can involve inserting, deleting, or modifying specific genes. It has applications in medicine (gene therapy), agriculture (GMO crops), and biotechnology. While it offers numerous benefits—such as treating genetic disorders, increasing crop yield, and improving disease resistance—it
