Tendencies of 31P chemical shifts changes in NMR spectra of nucleotide derivatives.

abstract：:'Linker scanning' has been used as an efficient method for systematically surveying a segment of DNA for functional elements by mutagenesis. A three-step PCR method was developed to simplify this process. In this method, a set of 'mutation primers' was made with 6 to 8 base substitutions in the center of the primers. ...
