DNA Molecules

Deoxyribonucleic acid, or DNA, is the component containing the blueprint that specifies the biological development and composition of every form of life. Its general structure is in the form of a double helix and is primarily made up of nucleic acids. DNA is a polymer strand of nucleotides that contain sequences using genetic codes. For most complex cells, DNA is actually located in the cell nucleus. The physical model of the DNA molecule has always been a source of great mystery to a lot of people. How can a tiny molecule be responsible for carrying all genetic information?

Embryonic Stem Cell Research: Overcoming The Ethical Barriers

With well-publicized declarations that embryonic stem cells may be the panacea for every disease and affliction that defies current medical treatments based on surgical procedures and drug-based therapies, vocal support for stem cell research continues to grow louder. Yet for the full potential to be realized, significantly more research is needed and ethical barriers must be overcome. The latest reports provide reason for hope that before long embryonic stem cell research will be able to be pursued to its fullest.

Scientist Hwang Woo Suk Falls Back to Earth

It's quite a sight to see a man rise to the very pinnacle of his vocation and then come falling back down to earth, disgraced, humbled and with his tail between his legs. Things would be infinitely worse if the arena where all this happened was one filled with back-biting and intrigue, such as the world of Science.

Biodiesel as an Alternative Fuel

Biodiesel fuel is a fuel made from the oil of certain oilseed crops such as soybean, canola, palm kernel, coconut, sunflower, safflower, corn and a hundreds of other oil producing crops. The oil is extracted by the use of a press. The oil is then mixed in specific proportions with other agents which causes a chemical reaction. The results of this reaction are two products, biodiesel and soap.
