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.

Recombinant DNA is the general name for a piece of DNA that has been created by the combination of at least two strands.Recombinant DNA molecules are sometimes called chimeric DNA, because they can be made of material from two different species, like the mythical chimera.ecombinant DNA is used to identify, map and sequence genes, and to determine their function. rDNA probes are employed in analyzing gene expression within individual cells, and throughout the tissues of whole organisms.
