## Other Factors that Include DNA Damage - UV radiation causes Thymine dimer (T-T) - Hydrocarbons that bind to DNA (DNA adducts) in burning coal/gasoline - Burnt meat - Drugs - Some chemotherapy ## DNA Repair A cell has several different mechanisms to recognize errors in DNA. The basic stages are: - Recognition - Removal - Replacement There are many types of DNA repair. DNA polymerase can read correct sequence from complementary strand to repair mistakes ## What happens if DNA errors are not repaired? - DNA contains genetic instructions - Alterations of the DNA can lead to mutations which can result in disease, such as cancer.
