本文研究了Ce ~(3+)和Mg ~(2+)离子诱导的DNA双链结构转变。通过原子力显微镜,不同类型的凝聚DNA结构观察到在Ce 3+或Mg 2+离子的存在下。结果表明,稀土离子与碱土金属离子在DNA缩合过程中存在一定的差异。
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.
