"Exploring Genetics: Genetics is the study of genes and attempts to explain what they are and how they work. Genes enable living organisms to inherit features from their ancestors. Genetics tries to identify which features are inherited and to explain how these features are passed from generation to generation. Genese are made from a long molecule called DNA (Deoxyribonucleic acid), which is copied and passed down the generations. DNA is made up of simple units that line up in a particular order within this long molecule. The main role of a DNA molecule is the long-term storage of information and it is often said to represent a set of blueprints, like a recipe or a code for a person. The History of Genetics: By the mid-1980s scientists were able to amplify DNA, enabling them to read accurately short sentences in the more than 3 billion word novel that is the human genome. Using these technologies, it took 13 years and $3 billion to piece together the first human genome. Now technology is revolutionising the analysis. The next goal which has already been almost achieved, is to sequence the first 1,000 complete genomes. It is expected that in the near future, machines capable of sequencing 100 human genomes in 10 days will be available. As we learn more about genomes, we can scan for the small differences between them, the differences that make each of us unique, these variations are called SNPs (single nucleotide polymorphisms). Some of these SNP's are linked to characteristics such as eye colour, that
