182:(RNS). ROS and RNS are known to cause DNA damage via oxidative processes. Figure 2 shows each of the reactive sites for the nucleic acids involved in adduction and damage, with each form of transfer distinguished by arrow color. These positions are of interest to researchers studying DNA adduct formation. Research has indicated that many different chemicals may change human DNA and that lifestyle and host characteristics can impact the extent of DNA damage. Humans are constantly exposed to a diverse combination of potentially dangerous substances that might cause DNA damage.

342:, but eating chicken does not have this risk. The increased risk of colon cancer from red meat may be due to higher increases in DNA adducts from digestion of red meat. When rats were fed either beef or chicken, three types of DNA adducts in colon tissue were significantly higher after consumption of beef than after consumption of chicken. These adducts were a type of methyl-cytosine (possibly N3-methyl-cytosine), an adduct of two malondialdehyde molecules with guanine, and carboxyl-adenine.
