How Do Carcinogens Affect DNA? In theory, a carcinogen could act by binding to DNA and causing a change in the sequence that is perpetuated during DNA replication. Current evidence suggests, however, that many permanent DNA sequence changes are induced by the very repair processes cells use to rid themselves of DNA damage. Can carcinogens
Is There A Cure For Mutation? Most treatment strategies for genetic disorders do not alter the underlying genetic mutation; however, a few disorders have been treated with gene therapy. This experimental technique involves changing a person’s genes to prevent or treat a disease. Can a mutation be permanent? A gene mutation is a permanent alteration
Can Mutated Genes Repair Themselves? Often, gene variants that could cause a genetic disorder are repaired by certain enzymes before the gene is expressed and an altered protein is produced. Each cell has a number of pathways through which enzymes recognize and repair errors in DNA. Can genes repair themselves? The only known function of
