RNA is a polymeric genetic bio-molecule found in all human beings. It is the main genetic material in many viruses. In this paper we test the mechanical properties of RNA NWs. We will find Youngs Modulus of RNA Nanowires (NWs) as a function of diameter with taking equilibrium strain, Poissons ratio and surface stress in consideration. As previously no study has been published regarding Youngs Modulus of RNA we take a theoretical approach towards it. We will predict the behavior of RNA NWs and see the resemblance to either semiconducting or metallic nature of NWs. This study extrapolates key factors in modelling RNA NWs for the creation of nanowires based aptasensors, genetics and other related applications.
