the pyramids of Egypt were probably built and how the knowledge of trigonometry and measurement were evolved in those days. What we seek‚ while we speculate and meditate is the gradual end to our ignorance. We have come a long way from worshiping the forces of nature to the present day scientific feats of our ability to get high resolution pictures from the surface of Mars. From the speculation of Heraclitus‚ Pythagoras‚ Socrates to renaissance of enlightenment ages‚ we have walked a long road studded

considered a major drug in modern society. This drug has risen to be an important drug because of its discovery‚ and the development of the antibiotic. Penicillin could not cure so many people if it was never discovered. Accidents are a major factor of how many discoveries are made‚ the accidents will usually then lead to further research. Jesse Lane from “Not-So Dumb Luck states”‚ “Necessity is not always the mother of invention; sometimes it’s happenstance that begets the most amazing discovery” (121)

Was the discovery of penicillin an accident? Who really discovered penicillin? Many believe that penicillin was discovered by Alexander Fleming‚ although he sparked the research for penicillin‚ he wasn’t the first. Penicillin had and still does have an effect on the medical world. Penicillin has a very rich history behind it‚ and it is still used world round. One significant story that led to the discovery of penicillin was the one of Alexander Fleming. Although Alexander Fleming is credited for

Running Head: DNA Testing DNA Testing CRJ 311 Forensics Timothy Knox November 4‚ 2012 Thesis DNA testing has become a major part of forensic science. It helps in so many areas of life. Catching criminals‚ freeing the innocent‚ determining paternity of children‚ amongst other things‚ are just a few ways DNA testing helps. It has a few cons like the financial burden of it. But in the end it is worth it. Without DNA there would be many offenders roaming the streets‚ while hundreds of innocents

AGROBACTERIUM MEDIATED TRANSFORMATION OF SOYBEAN (GLYCINE MAX L.): SOME CONDITIONS STANDARDIZATION Abstract Present study was aimed to standardize some transformation conditions for soybean cultivar NARC-4 using Agrobacterium tumefaciens strain EHA 101 harboring pGUSintNPTII. Soybean half seed cotyledonary node method was opted. It was found that explant preparation in Agro-suspension culture resulted in highest transformation efficiency (48.3%) than in infection medium and water. One

ions -DNA replication minimizes errors such as the DNA that is duplicated but changes in the DNA do occur‚ producing mutations. Although most mutations are either neutral or harmful they are also the raw material for evolution. Such mutations from alleles‚ alternate forms of a given gene that may produce differences in structure or function such as black‚ brown or blond hair in humans‚ or different mating calls in frogs. Stages of Mitosis~ 1)Parent cell. 2)Chromosomes make identical copies

The discovery of Uranus‚ or "George’s Star" as it was originally called‚ was a revolutionary event in the field of astronomy. But to understand the significance of this discover‚ we must understand the conditions that exsisted just before and during this landmark milestone. Up to this point‚ several planets‚ those that are visible to the naked eye‚ and with out the aids that modern technology allow us‚ had been identified "before recorded history"‚ as an article about the discovery in "Science and
