The I-V characteristics of G4 DNA molecule in applied magnetic and electric fields has been calculated. We use DNA molecule in the form of stacked of 32 guanine quadruplex (G4) structures. The DNA molecule is contacted to the metallic electrode at both ends. The system under investigation is modeled using tight-binding Hamiltonian approach. Magnetic and electric field affects electron hopping constant following Peirels Phase Factor and Miller-Abraham, respectively. The result shows slight current increment with the magnetic field and current increment with electric fields after certain voltage value.
