Some genetic mutations can be completely harmless, while others are life-altering. Mutations happen when DNA is copied incorrectly. This causes an irregularity in the DNA. Mutations are permanent changes to genetic material that can be passed on to offspring. These changes happen randomly and can occur in any type of gene.
