This oxidative stress can directly damage DNA. It is the associated repairing of the oxidatively damaged DNA that sometimes fails, thus creating a mutation in the DNA. 3) Direct attachment of chemicals to DNA forming DNA Adducts.These 'adducts' must be removed from the DNA by DNA Repair mechanisms.t is the associated repairing of the oxidatively damaged DNA that sometimes fails, thus creating a mutation in the DNA. 3) Direct attachment of chemicals to DNA forming DNA Adducts.

It is found principally in the nucleus of all cells where it forms part of the chromosome, or in the cytoplasm of cells lacking a nucleus, such as bacteria.NA, n an acronym for deoxyribonucleic acid. A type of nucleic acid that contains genetic instructions for the development of cellular life forms. Capable of replicating itself and of producing another type of nucleic acid known as RNA. n the DNA specific to a bacterial strain.
