Gene therapy is a medical procedure that aims to treat or prevent diseases by modifying or replacing a person’s genes. Genes are like instruction manuals for our bodies, and when they have errors or mutations, it can lead to various health problems. Gene therapy works to fix these issues, ultimately improving a person’s health.
Our genetic material is the collection of instructions (genes) in our DNA that determine our traits and functions. Gene therapy involves making changes to this genetic material to correct errors or introduce beneficial modifications.
DNA is like a biological code that contains all the information needed to build and maintain our bodies. Genes are specific sections of this code that carry instructions for making proteins, the building blocks of our bodies.
