    amino 477-30-5 in the pure hydrophilic gene chain. Resistance Rn is same for all hydrophobic and hydrophilic amino acids.
    Now the recurrence relations for gene chain consists of hydrophobic and hydrophilic residues both, are as follows:
    where Gn = Nn/Dn, Nn and Dn are the polynomials of degree n for both hydrophilic and hydrophobic genes. Therefore using these expressions, the transfer function can easily be computed for the electrical system model of amino acid chain of any arbitrary length.
    3. Results and discussions
    The genetic attributes are investigated by modeling sensor network for gene, which is tested on 40 gene databases (25 cancerous or hy-drophilic and 15 non-cancerous or hydrophobic) (Table 2 and Table 3) and the databases for the genes are downloaded from public domain (;; http://www. The electrical responses of the sensor are simulated in MATLAB (version R2009b) environment.

    values in the frequency range of 1 Hz to 1 MHz as detailed in Table 4. There are no marked differences observed in amplitude values; hence only the phase values of all the electrical system models representing genes are considered. 477-30-5 The plots in Fig. 2 are obtained by cascading the amino acid circuit models, where each amino acid having constant Rb of 7 Ω for backbone circuit and LSC or CSC of different values depending on hydropathy index values of hydrophobic or hydrophilic amino acid for side chain. Fig. 2 exhibits significant differences in phase responses between cancerous and non-cancerous genes and the phase values are markedly distinguished from each other within the frequency range of 50 kHz to 1 MHz.
    The simulated results (Fig. 2) for cancerous genes show negative phase at higher frequency as they are modeled by cascaded RC parallel circuit, which indicates these genes contain large amount of hydrophilic or polar amino acids. Whereas non-cancerous genes exhibit positive phase at higher frequency since they realized by RL parallel circuit, indicates they made up of large amount of hydrophobic amino acids. Therefore the cancerous and non-cancerous genes exhibit polar and 
    nonpolar characteristics respectively, which are clearly observed by the corresponding simulated phase responses, and the sensor realization is truly matched with the biological features (Stranzl et al., 2012) of genes.
    3.2. Performance evaluation of sensor characteristics
    The gene datasets, collected from the national website for health-care, are classified by modeling sensor. The sensor performance is judged by receiver operating characteristic (ROC) curve and analyzed using the following measurement metrics:
    • Accuracy is the ratio of the number of correctly classified genes to the total number of genes.
    • True positive rate or sensitivity (TPR) is the ratio of the number of correctly classified genes from the positive class (TP) i.e. cancer to the number of all genes from the positive class (TP + FN).
