Maverick scientists are within the technique of cloning people, and the human genome series is on the market on the net. Fifty years in the past we didn't be aware of what a gene used to be; this present day the remarkable energy of genetics is being published on an unsuspecting public, and with it an entire sequence of moral dilemmas undreamt of even ten years in the past. The query now has develop into now not "can we?" yet "should we?" by way of demystifying genetic engineering and exploring the elemental biology of the dwelling global, A negative attractiveness is Born explains how clones and cloning know-how are in lots of methods extensions of approaches that ensue consistently in nature. Used properly those procedures have the aptitude to convey huge, immense merits; abused, they bring with them power hazards that we forget about at our peril.

Sample text

Some proteins signal the cell to start dividing, many more are involved in the process of division itself, Copyright 2003 Taylor & Francis 49 50 The health of the nation whereas others are responsible for ending the process when the two new cells have been formed. Cancer arises when one or more of these proteins becomes defective and this balance is disturbed – cells either start to divide when they should not or continue to divide after they should have stopped. With so many proteins involved in the process, small wonder that there are more than 200 different ways in which the human body can experience uncontrolled cell division – each one of which gives rise to a different form of cancer.

It has to be transported around the body but it does not dissolve in the watery part of our blood, so the body encases the cholesterol to facilitate its transport through the bloodstream. Special proteins embedded in these particles enable them to deliver their valuable contents by docking onto receptor proteins in the cell membranes where it is needed. At the last count there were more than a dozen different genes encoding proteins involved in the complex production, transport and release of cholesterol around the body.

Cancer Cancer describes a condition of uncontrolled cell division in a particular part of the body. Although β€˜war’ was declared on this killer over 30 years ago, the word still strikes fear into our collective consciousness. The reason is that the simplicity of the description belies the fact that cancer is neither a simple target nor indeed even a single disease. That is why, despite the fact that hardly a year goes by without a claim of a new breakthrough in our fight against the disease, the war goes on.
