How tissue/cells designed to protect and repair DNA:
Question: Discuss common pathways of DNA mutation – chemical [examples / deamination, alkylation, etc] – slippage during replication – keto/enol flux / physical energy.
Question: Discuss the repair mechanisms – methyl directed mismatch / nucleotide excision / base excision repairs / GST - and how mutation in them lead to inheritable risk for developing cancer.
