Notes

'In 'DNA & genetic engineering', we see how DNA is put together and how its code is read and acted upon by the cell to make proteins... The book explains why genetic engineers aim to alter genes, or to transfer genes from one organism to another, and how they do this. It also looks at how genetic engineering has led to the development of 'designer' plants, and the creation of transgenic animals to aid the study of human diseases. Finally, it explores gene therapy, and the controversial areas of stem cell research and cloning'--Back cover
