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.

Deoxyribonucleic acid (/diËÉksiËraÉªbÉµ.njuËËkleÉª.É¨k ËaesÉªd/ ; ËÃ¦SÉªD) dna is a molecule that carries most of the genetic instructions used in the, development functioning and reproduction of all known living organisms and many. virusesranscription is carried out by a DNA-dependent RNA polymerase that copies the sequence of a DNA strand into RNA. To begin transcribing a gene, the RNA polymerase binds to a sequence of DNA called a promoter and separates the DNA strands.
