The two Phillips Petroleum Company chemists had made the first crystalline polypropene. While HDPE existed in 1951, the process for manufacturing it required extremely high pressures. Banks and Hogan solved that challenge and wrote a patent idea. The discovery has led to the production of many of the products consumers take for granted today ranging from the baby bottle to milk jugs and from toys to tools. The genes will then replicate.
Genetic engineering has many practical applications in medicine and agriculture.
For example, most insulin taken by diabetics is genetically engineered. Human growth hormones and other human gene products with specific medical uses also are available only because they can be made through cloning methods. Improving genetically engineered crops has been helpful in addressing global food supply problems. It also can be used to help understand the mysteries of cell biology. His high-pressure steam engine advanced transportation, propelling steamboats up the Mississippi and Ohio rivers.
