Abstract
The ionization specific influence of nitrogen bases on thermostability of AT- and GC-pairs of DNA has been investigated by the method of DNAs melting temperature analysis. It has been shown that the change of temperature interval of DNA helix-coil transition when changing pH environment is due to specific ionization of AT- and GC-pairs of nitrogen bases.
摘要
通过DNA解链温度分析方法，研究了氮碱基对DNA中AT和GC碱基对热稳定性的电离特异性影响。结果表明，改变pH环境时DNA螺旋-线圈转变温度区间的变化是由于氮碱基的AT和GC碱基对的特异性电离所致。
