WebDec 30, 2024 · Depurination of guanines (or adenines) is a common DNA lesion. Three of the four DNA bases, adenine, guanine, and cytosine, contain amine groups that can be lost in a variety of pH and temperature-dependent reactions that convert the bases to hypoxanthine, xanthine, and uracil, respectively. WebDNA replication begins with the unwinding of the DNA strands. Through the action of the enzyme helicase , a portion of the helix will “open” as the two strands separate. The point at which the strands separate is referred …
