  Molecular cloning is a technique used to manipulate an organism’s genome using biotechnology. This provides a way of overcoming barriers to gene transfer between species. The aim of this study was to remove a gene from one organism and transfer it to another so that the gene is expressed in the new host. A Nuclear inclusion (NIa) protease gene coding for an autocatalytic protease obtained from Cowpea aphid-borne mosaic virus (CABMV) was fused with the green fluorescence protein gene in a pUC57 plasmid. The fusion was then cloned into a pUC18 expression vector via the SmaI site. Escherichia coli (E. coli) NM522 cells were transformed by this recombinant vector. Protein expression was induced using Isopropyl β-D-thiogalactopyranoside (IPTG). The protein sample was analysed using sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) analysis which showed that the protein was successfully expressed and cleaved out of the fusion vector system by the protease.
