Result shows the abilities of the extract and standard thiourea to inhibit hydroxyl radical-mediated deoxyribose degradation in a Fe[Cl.sub.3]-EDTA-ascorbic acid and [H.sub.2][O.sub.2] reaction mixture.
ROS induces damage to cellular DNA, including the rupture of deoxyribose rings, the appearance of apurinic and apyrimidinic sites, single-and double-strand breaks, DNA protein crosslinks, and formation of oxidized bases [13].
Hydroxyl radical ([sup.*]OH) was determined by the inhibition of deoxyribose degradation [37].
Then, the deoxyribose hydroxyl group at the broken end attacks the enzyme-DNA linkage, forming the DNA phosphodiester linkage and freeing the enzyme for the next round of reactions (Wang 1994).
Each nucleotide (A, G, C, and T) contains 3 components [ILLUSTRATION FOR FIGURE 1 OMITTED]: a deoxyribose (a five-carbon sugar), a triphosphate group, and a base, which can be adenine, thymine, guanine, or cytosine.
It is well known that neither [O.sub.2.sup.*-] nor [H.sub.2][O.sub.2] is capable of interacting with either deoxyribose or the base portions of DNA; this suggests that the secondarily derived *OH radical may be the primary reactive species.
They are composed of sugars (deoxyribose), phosphate groups, and nucleobase attached to the sugars.

A Structure for Deoxyribose Nucleic Acid," published in Nature in 1953, the two scientists described the double-helical form of the molecule, shaped like a twisted ladder, in which each rung is made up of four nucleotides: adenine, thymine, cytosine, and guanine (typically abbreviated as A, T, C, and G).
Its labile phosphodiester backbone and the tendency for base cleavage from deoxyribose makes intact volatilization of larger strands challenging [181.
