KAM FAI CHEUNG Generating recombinant DNA to study the trafficking of histone H2B, PFKFB3 and FZR1 protein in mammalian cell Abstract Recombinant DNA is essential for us to study the function of a gene and its ways of ex-pression in the cell by separating the gene of interest and transferring to another DNA contains regulatory control sequences. We tried to produce a vector from pSNAPm, us-ing restriction enzymes of XhoI, ClaI and EcoRI. Sticky ends were made to recombine with the CLIP-tag sequence from pCLIP-H2B and the sequence encoding FZR1 protein. E. coli played an important role in the DNA recombination from DNA cloning to the expres-sion of the recombined gene. The recombination between pSNAPm and pCLIP-H2B as well as pSNAPm and FZR1 were successful, determined by showing ampicillin re-sistance in E. coli.
