Nucleoside and nucleobase analogs can integrate into DNA, potentially causing mutations. This review covers their current study status and base mispairing mechanisms.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Genetics

Background:

  • Nucleoside and nucleobase analogs mimic natural DNA building blocks.
  • Incorporation into cellular DNA can disrupt normal genetic processes.

Purpose of the Study:

  • To review the current research status of nucleoside and nucleobase analogs.
  • To discuss the base mispairing mechanisms of these analogs.

Main Methods:

  • Literature review of biochemical and biophysical studies.
  • Analysis of mechanisms underlying base mispairing.

Main Results:

  • Nucleoside analogs can be incorporated into DNA.
  • These analogs can lead to cellular mutations upon proliferation.
