Throwing a loop to silence gene expression

All human cells contain essentially the same DNA sequence – their genetic information. How is it possible that shapes and functions of cells in the different parts of the body are so different? While every cell's DNA contains ...

Genetics of cancer: Non-coding DNA can finally be decoded

Cancer is a disease of the genome resulting from a combination of genetic modifications (or mutations). We inherit from our parents strong or weak predispositions to developing certain kinds of cancer; in addition, we also ...

Genetic engineering

Genetic engineering, recombinant DNA technology, genetic modification/manipulation (GM) and gene splicing are terms that apply to the direct manipulation of an organism's genes. Genetic engineering is different from traditional breeding, where the organism's genes are manipulated indirectly. Genetic engineering uses the techniques of molecular cloning and transformation to alter the structure and characteristics of genes directly. Genetic engineering techniques have found some successes in numerous applications. Some examples are in improving crop technology, the manufacture of synthetic human insulin through the use of modified bacteria, the manufacture of erythropoietin in hamster ovary cells, and the production of new types of experimental mice such as the oncomouse (cancer mouse) for research.

The term "genetic engineering" was coined in Jack Williamson's science fiction novel Dragon's Island, published in 1951, two years before James Watson and Francis Crick showed that DNA could be the medium of transmission of genetic information.
