Biotechnology: Principles and Processes
Insulin used to come from the pancreas of cattle and pigs. Today a bacterium makes it. How can a cell of one species be told to make a protein of another? This chapter shows you the tools: enzymes that cut DNA at a chosen place, enzymes that join it, and small circles of DNA that carry a gene into a host. Then you follow the steps of the work, from isolating the DNA to copying a gene by PCR, putting it into a cell and picking out the cells that took it. You end in the bioreactor, where the product is made in large amounts. Python counts fragments, copies and colonies exactly. It serves the Indian syllabus (NCERT, NEET) and the matching topic of A-Level, IB and AP. A fourth course goes deeper, for readers who want the level of A-Level Biology, IB Higher Level and the Olympiad.
