Theoretical Methods for coding a strand of DNA bases and nucleotides with C۲Fe+ , A DFT study

DNA strands are essential in a cell for growth, metabolism regulation and carrying genetic information bases to new generations,in every creatures . The function of DNA bases is a ۰ and ۱ system. In this theoretical research , we try to make two other ۰ and۱ systems for DNA bases .In both methods, C۲Fe+ is attached to DNA bases and nucleotides like a flag to make derivatives. Inthe first method NMR susceptibility and Magnetization of pristine DNA bases, nucleotides and their C۲Fe+ varieties aredetermined theoretically by using Gauss view and Gaussian programs. With effect of a magnetic field (H) and NMRsusceptibility of these compounds, their calculate magnetizations , certain signals can be created as a mark of DNA bases andtheir compounds. These resulted not only can be considered as a method to make a new ۰ and ۱ coding system. In the secondmethod, by using Gauss view and Gaussian programs the theoretically UV-Visible spectrum of pristine DNA bases, nucleotidesand their C۲Fe+ varieties are determined which the spectrum absorption of the pristine compounds are in different range with theabsorption range of C۲Fe+ varieties. With a little change in spectrophotometer construction another ۰ and ۱ coding system canbe created, again.
