WebMay 30, 2024 · Apurinic/apyrimidinic (AP, or abasic) sites in DNA are one of the most common forms of DNA damage. AP sites are reactive and form cross-links to both proteins and DNA, are prone to strand breakage, and inhibit DNA replication and transcription. WebThe two strands go in opposite directions, with the nitrogen-containing bases facing inward to make the steps or rungs of the staircase and the sugar-phosphate backbone making up the outside walls of the helix. The hydrogen bonds between the nitrogen bases keep the two strands of DNA together and help keep the DNA molecule stable and whole.
