Genetically modified crops (GMCs‚ GM crops‚ or biotech crops) are plants‚ the DNA of which has been modified using genetic engineering techniques. In most cases the aim is to introduce a new trait to the plant which does not occur naturally in the species. Examples include resistance to certain pests‚ diseases‚ or environmental conditions‚ or resistance to chemical treatments (e.g. resistance to a herbicide)‚ or the production of a certain nutrient or pharmaceutical agent. Genetic engineering techniques

Also found in Willey et al (2014) is some characteristics of enterics such as they all degrade sugars by means of the Embden-Meyerhof pathway‚ they produce plasmid-encoded proteins and that some of them perform mixed acid fermentation‚ some use enzyme systems like formate dehydrogenase and pyruvate formate-lyase (PFL) The first thing that had to be done was the streak plating to isolate the bacterium‚ then the

Genetically Modified Foods: a Growing Concern? Living in America‚ we sometimes forget what a huge problem malnutrition and starvation are in other parts of the world. It ’s estimated that over 852 million people in the world are severely food deprived. Now‚ imagine a world where no one goes hungry‚ a farmer ’s crop can survive a long drought or an early frost and still produce a large harvest‚ and harmful insects and weeds cannot survive in the same field as a crop. Imagine a world where malnutrition

What exactly is a prokaryote? Why are they so important in the scientific universe? To the amazement of many‚ prokaryotes are some of the most important organisms on Earth‚ and may have been the first to ever thrive on planet Earth. From what modern scientists know‚ prokaryotes were the first organisms on Earth‚ surviving millions of years on the treacherous terrain that was early Earth before humans ever came into existence. Prokaryotes are known for their incredible abilities to survive in the
