Who Discovered Genetic Engineeing?
Genetic Engineering is a modification in the program of the genes in order to grow organisms. The genetic engineering is the way to choose between the traits of the organism, and choose the desired traits to introduce them in the targeted plant or animal. In the year 1952, Alferd Hershey ( 1908-1997), the American bacteriologist … Continue reading
Who Discovered The DNA?
DNA is deoxyribonucleic acid , it is the molecule in the living organisms that is responsible for making every species different than the other species and allows its offspring to carry the same characteristics. The DNA is found in the nucleus of every cell of the living organism. The DNA molecule is called the chromosome. … Continue reading

Robotic Nano-Spiders Made of DNA Molecules
A group of scientists from Columbia University managed to invent extremely small spider robots measuring about 4nm across. If you wish to compare, these nano robots are about 100,000 times smaller than the diameter of a human hair. It would be interesting to note that the spider robots are made of DNA molecules. They can … Continue reading
