Area of Science:

  • Genetics
  • Molecular Biology
  • Genomics

Background:

  • DNA repair mechanisms are essential for preserving genome integrity against various damaging agents.
  • Over 70 human DNA repair genes across five major pathways are identified, with known locations and sequences.
  • Gaps exist in understanding the precise functions and health implications of these genes.

Purpose of the Study:

  • To consolidate current knowledge on human DNA repair genes.
  • To compare human DNA repair genes with their counterparts in model organisms (bacteria, yeast, rodents).
  • To discuss the association between DNA repair gene defects and human diseases.

Main Methods:

  • Literature review and data synthesis.
  • Comparative analysis of DNA repair gene functions across species.
