Genetic Engineering Dna Molecules
633 wordsTwo years ago, genetically engineered bacteria, which unexpectedly killed beneficial soil fungi, escaped into sewers through human error and have become toxic to plants and survived when expected not to. 3 These are the sorts of consequences that come with playing God. DNA (deoxyribonucleic acid) - the chemical compound that makes up the genes and determines the type of proteins a cell can make - is the core of genetic engineering. It can be manipulated in ways we could never dream of such as a ...

Animals There Is A Good Epilepsy Drug Brain
383 wordsEverybody knows cocaine is bad for you. So why do so many people take it? It gets you high. You feel good for a little while. Then youre sad again. Teenagers have this problem a lot. Scientists have found a way to maybe prevent highs when using cocaine. Actually, they found a way in animals, and they are hoping to use it on humans. The team showed that the epilepsy drug gamma vinyl-GABA, or GVG, blocked cocaine's effect in the brains of primates, including the process that causes a "high" feelin...

Liquid Hydrogen Natural Gas
725 wordsHelium (Greek helios, "sun"), symbol He, inert, colorless, odorless gas element. In group 18 of the periodic table, helium is one of the noble gases. The atomic number of helium is 2. Pierre Janssen discovered helium in the spectrum of the corona of the sun during an eclipse in 1868. Shortly after it was identified as an element and named by the chemist Sir Edward Franklin and the British astronomer Sir Joseph Norman Lockyer. The gas was first isolated from terrestrial sources in 1895 by the Bri...

Material On The Life Of Charles Darwin
979 wordsCharles Darwin was born in Shrewsbury, Shropshire. He was the son of Robert Waring Darwin and his wife Susannah, and the grandson of the scientist Erasmus Darwin. His mother died when he was eight years old, and he was brought up by his sister. He was taught the classics at Shrewsbury, then sent to Edinburgh to study medicine, which he hated. Like many modern students Darwin only excelled in subjects that intrigued him. Although his father was a physician, Darwin was uninterested in medicine and...

White Blood Cells Cell Wall
1,297 wordsBacteria is a simple organism that consists of one cell. They are among the smallest living thing on earth. Most bacteria measures from about 0. 3 to 2. 0 microns in diameter, and can only be seen through a microscope. Scientist classify bacteria according to shape. Cocci are round and sometimes linked together. Bacilli look like rods, and Vibrios resembles bent rods. There are two types of spiral-shaped bacteria, spirochetes and spirilla. Bacteria exist almost anywhere you can think of. There a...

Stem Cell Immune System
393 wordsGeneric Heart Engineering To engineer a heart, the pathways to its formation through stem cells must first be discovered through one genome line that is as healthy as possible (i. e. no signs of an genetic disorders, especially related to oncogenes, no family history of heart problems). Then a process could be made to grow a heart in vitro through the use of the right cell signaling, transcription factors and hormones. After this process is perfected, the genome could be screened again for any d...

Organic Molecules Life Span
525 wordsThe expression of genes is very complicated and is regulated by a number of things. Something that has a major effect on enzyme regulation and stability is temperature. Since enzymes are biochemical catalysts, made up at least partially of protein, they are sensitive in varying degrees to heat. Raising temperatures of the environment generally multiplies the degree of activity by the enzyme. Once an optimum temperature has been reached, however, temperatures that are too high will denature the e...

Fertilized Egg Y Chromosome
358 wordsSex Chromosomes Chromosomes are the aggregates of genes, carrying heredity information. They comprise of proteins and DNA, and are located within the cells' nucleus. Human cells contain 22 pairs autosomes and only one pair of sex chromosomes. These sex chromosomes, the X and the Y chromosomes determine the sex of the individual, or the gender. In such a way, there are two sex chromosomes in a human somatic cell: XX in female and XY in male. A human germ cell contains only one sex chromosome, whi...
