Private Notes
Everybody looks different, apart from identical twins, and many of the differences are inherited.
Living matter is made from a complex mixture of chemicals, some small like salts, sugars and fats and others large and complicated such as protein and DNA.
How can we isolate and study genes one at a time?
The body protects itself against infection by bacteria, viruses, molds and parasites by having a system for recognising these invading organisms as foreign.
Cancer can occur when the regulation of cells in the body goes astray. Any tissue can be affected but some are more likely to become cancerous than others.
Genetics will eventually identify all the human genes and their functions. How far will this take us in explaining the infinite variety of mankind?
