Miller and Urey tried to duplicate the ‘primordial soup’, thereby attempting to prove that that alone could possibly be how life originated on Earth. […]

Genetic modification in animals is easily accepted. However, when it comes to humans, it raises ethical questions such as should we alter our genetic makeup not only to rectify a defect but also to enhance our capabilities or make ourselves super human? […]

Cancer is an acquired genetic disease that occurs when cells lose the ability to die. Most of the time, regulatory processes orchestrate the death of cells that are defective. In cancer, the cells lose the ability to die. […]

Viral vectors are an effective way to reprogram cells to duplicate correct DNA and make a specific protein, the one that it should have been producing all along. […]

As we learn new ways of altering genes, there seems to be limitless prospects for genetically engineered products. However, the most crucial applications of genetic engineering are the cures of inherited genetic diseases in humans. […]

While we can’t yet clone animals from just any single cell, the techniques may be used to preserve or even increase Earth’s biodiversity, or to preserve libraries of genetic material for organisms now threatened with extinction. […]

There are techniques that can be used to compare, quickly and accurately, the DNA from different organisms. Moreover, all sorts of things to manipulate DNA can be done in laboratories now. […]

Biological information is stored in deoxyribonucleic acid, or DNA. The genetic code converts the four-letter alphabet of DNA into a correct sequence of amino acids, and it uses ribonucleic acid, or RNA, to do this. […]

Scientists can manipulate and analyze tiny amounts of DNA through a simple technique called the polymerase chain reaction (PCR). This technique has found many applications in science and technology. […]
