Gene expression and its application in biotechnology

Advances in biotechnology has been the subject of praise for a decade now, this is due to techniques such as gene expression which contributed immensely success genetic engineering, medical advancement, vaccine production and agriculture. Gene become very important tool overall improvement quality life. This paper tries look into development last forty years highlight how technological advancements study brought about improvements focal point. Technological associated with northern blotting, western enzyme-linked immunosobent assays, Polymerase Chain Reaction (PCR) technology emphasis on quantitative PCR, differential protein display technique DNA sequencing hybridization arrays macroarrays microarrays facilitating will be discussed.
