Biotinylation of Deoxyguanosine at the Abasic Site in Double-Stranded Oligodeoxynucleotides

Figure 3

The DNA sequence showed the replacement of guanine to adenine with an asterisk symbol. Replacement of guanine with adenine generated by the activity of the terminal deoxynucleotidyl transferase of Taq polymerase was detected by DNA sequencing analysis.
