What is a DNA mutation?
DNA is the genetic material that always undergoes various chemical reactions and always copies DNA. Changes in DNA structure are called DNA mutations that can occur during the DNA replication process. To stabilize this, DNA has the ability to repair errors that occur in itself. If there are enough DNA mutations and the DNA does not have time to repair itself, there will be genetic expression abnormalities and even cause genetic diseases.
