DNA replication ensures accurate genome duplication each cell cycle. This review covers regulation from prereplication complex formation to checkpoint pathways maintaining genomic stability.

Area of Science:

  • Molecular Biology
  • Cell Cycle Regulation
  • Genomics

Background:

  • DNA replication is essential for cell division, occurring during S phase.
  • Accurate and timely genome duplication is critical for preventing genomic instability.
  • Eukaryotic genome complexity necessitates highly regulated replication processes.

Purpose of the Study:

  • To review the regulation of DNA replication in eukaryotic cells.
  • To integrate structural data from prokaryotic systems to understand eukaryotic replication.
  • To discuss replication licensing and checkpoint control mechanisms.

Main Methods:

  • Literature review of DNA replication mechanisms.
  • Analysis of structural data from archaeal and bacterial replication proteins.
