The Difference between Rare Earth Ions and Alkaline Earth Metal Ions in DNA Condensation Process

Article Preview

Abstract:

The structural transition of DNA double-stranded induced by Ce3+ or Mg2+ ions was investigated in this paper. By atomic force microscopy, different types of condensed DNA structures were observed at the presence of Ce3+ or Mg2+ ions. The results show that there are some differences between rare earth ions and alkaline earth metal ions in the DNA condensation process.
