1953 – DNA – Watson and Crick

In 1953, James Watson and Francis Crick published an article in the journal, “Nature”. The article, titled “Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid”, described the DNA double helix structure which stores and replicates genetic information. When the two identical halves of the helix separate, the chemical bonds which held them […]

2003 – Human Genome project completed

The Human Genome Project – [genome.gov] The Human Genome Project (HGP) was one of the great feats of exploration in history – an inward voyage of discovery rather than an outward exploration of the planet or the cosmos; an international research effort to sequence and map all of the genes – together known as the […]

DNA Ink Branding

From footballs to food to luxury goods, branding an item with ink that contains a specific DNA marker is becoming the latest technique to stop counterfeiters. Plant DNA Helps Catch Criminals and Thwart Counterfeiters – [popsci.com] Counterfeiters are skilled at making knockoffs of even the most high-end tech and luxury products. But one European luxury […]

Animals With Bonus Features

A mouse can be genetically modified to run twice as far as normal mice or to not fear cats. As biologists develop better techniques to alter DNA and to add the altered DNA into cells so it can replicate, genetic engineering is becoming more practical. Animals that breed faster, have greater resistance against diseases and […]

Rebuilding Our Bodies

We now have the ability to rebuild our bodies; at least in a limited sense, but that limitation is shrinking rapidly. Prosthetic Replacements Artificial replacement limbs and dentures have been used for thousands of years. Roman Capua Leg – [wikipedia.org] Prosthetic replacements have dramatically improved their functionality and their human-like appearance with increases in technological […]

Human Genome Project

The purpose of the Human Genome Project was to determine the complete sequence of 3 billion DNA sub-units, identify all human genes and make the information available. Human Genome Project Information – [ornl.gov] Completed in 2003, the Human Genome Project (HGP) was a 13-year project coordinated by the U.S. Department of Energy and the National […]

Triple Helix

This Scientific American article discusses the idea of creating artificial self replicating genetic material that could be better than DNA. Triple Helix: Designing a New Molecule of Life Peptide nucleic acid, a synthetic hybrid of protein and DNA, could form the basis of a new class of drugs—and of artificial life unlike anything found in […]
