- 8461: Genetic Engineering
- ... tumors will turn to harmless dumps of organic material, that can be filtered out by the body. DNA scissors will affect things that antibiotics cannot, like AIDS. (Not even AIDS can function without DNA). One day the only thing that will stand between medical diseases and their cure will be the analysis of their DNA. Genetics now offers a new way to solve the general problems of the world. First, genetic ...
- 8462: Flourescence In-situ Hybridisation and Its Advantages
- ... FISH is that the parents get a much quicker test result than amniocentesis. After the sample is taken, amniocentesis can take up to three weeks before a test can be administered. With FISH, a same day result is given, which is much more convenient to the parents. Additionally, FISH is a simpler process. It uses specially prepared molecules which bind to specific regions of DNA. To find a particular gene, the ...
- 8463: The Effects of Foreign Species Introduction On An Ecosystem
- The Effects of Foreign Species Introduction On An Ecosystem The effects of foreign species introduction into an ecosystem are very profound. From small microorganisms to species of large mammals, many foreign species introductions occur every day. New implications of their introduction are found just as often. When a foreign species is introduced into an ecosystem, often the ecosystem contains no natural predators for the new species. This lack of predators sometimes ...
- 8464: Diverrsity of Plants
- ... Unlike the highly specific hormones of animals, plant hormones are not produced in definite organs nor do they have definite target areas. They stimulate or inhibit growth in response to environmental clues such as light, day length, temperature, touch, and gravity and thus allow plants to respond efficiently to environmental demands by growing in specific directions, producing flowers, or displaying other responses appropriate to their survival in a particular habitat. Tropisms ...

- 8466: Bioluminescence in Fungi
- ... Oxygen - as a catalyst A simplified formula of the bioluminescent reaction: ATP(energy) + Luciferin (substrate)+ Luciferase(enzyme) + O2(oxidizer) == == light (protons) The bioluminescent reaction occurs in two basic stages: 1) The reaction involves a substrate (D-Luciferin), combining with ATP, and oxygen which is controlled by the enzyme(Luciferase). Luciferins and Luciferase differ chemically in different organisms but they all require molecular energy (ATP) for the reaction. 2) The chemical energy ...

- 8468: The Big Bang
- ... cool, and fill the expanding universe uniformly. By now it would strike Earth as microwave radiation. In 1965 physicists Arno Penzias and Robert Wilson detected microwave radiation coming equally from all directions in the sky, day and night, all year.3 And so it appears that astronomers have detected the fireball radiation that was produced by the Big Bang. This casts serious doubt on the Steady State model. The Steady State ...
