Study Notes
Types of DNA Damage
- Replication errors can cause mismatch repair, which results in incorrect base pairing
- Ionizing radiation can cause double-strand breaks in DNA
- UV radiation can cause thymine-thymine dimers, which are a type of DNA lesion
DNA Repair Mechanisms
- Single-strand breaks are repaired by the base excision repair (BER) pathway
- UV radiation-induced DNA damage is repaired by the nucleotide excision repair (NER) pathway
- Oxidative stress can cause oxidative lesions, such as 8-oxoG, which are repaired by the base excision repair (BER) pathway
