The term recombinant DNA technology, DNA cloning, molecular cloning, or gene cloning all refers to the same process. Gene cloning is a set of experimental methods in molecular biology and useful in many areas of research and for biomedical applications. It is the production of exact copies (clones) of a particular gene or DNA sequence using genetic engineering techniques. cDNA is synthesized by using template RNA isolated from blood sample (human). GAPDH (Glyceraldehyde 3-phosphate dehydrogenase) is one of the most commonly used housekeeping genes used in comparisons of gene expression data. Amplify the gene (GAPDH) using primer forward and reverse with the sequence of 5’-TGATGACATCAAGAAGGTGGTGAA-3’ and 5’-TCCTTGGAGGCCATGTGGGCCAT- 3’.pUC18 high copy cloning vector for replication in E. coli, suitable for “blue-white screening” technique and cleaved with the help of SmaI restriction enzyme. Modern cloning vectors include selectable markers (most frequently antibiotic resistant marker) that allow only cells in which the vector but necessarily the insert has been transfected to grow. Additionally the cloning vectors may contain color selection markers which provide blue/white screening (i.e. alpha complementation) on X- Gal and IPTG containing medium.
