The reaction of ROS with DNA mainly comes about due to reactions of OH with pyrimidines, purines, or sugars in DNA, and one of the most frequent oxidative DNA lesions is 8-hydroxy-2-deoxyguanosine (8-OHdG)37. Therefore, 8-OHdG is known to be a biomarker for oxidative damage of DNA...
2. Understand the Types of Bases: The nitrogenous bases in DNA are categorized into two groups: purines and pyrimidines. Purines include adenine (A) and guanine (G), while pyrimidines include cytosine (C) and thymine (T). 3. Base Pairing Rules: According to Chargaff's rules, purines ...
We used a series of dNTP analogues in conjunction with templates containing modified bases to elucidate the role that N2 of a purine plays during dNTP polymerization by human DNA polymerase α. Removing N2 from dGTP had small effects during correct incorporation opposite C but specifically increased...
This paper shows that repair proteins can also participate in the signalling of apoptosis. CAS PubMed PubMed Central Google Scholar Plosky, B. et al. Base excision repair and nucleotide excision repair contribute to the removal of N-methylpurines from active genes. DNA Repair (Amst.) 1, ...
