Genetic engineering, genetic modification (GM), and the now-deprecated gene splicing are terms for the process of manipulating genes, usually outside the organism's normal reproductive process.\n\nIt involves the isolation, manipulation and reintroduction of DNA into cells or model organisms, usually to express a protein. The aim is to introduce new characteristics or attributes physiologically or physically, such as making a crop resistant to a herbicide, introducing a novel trait, or producing a new protein or enzyme. Examples can include the production of human insulin through the use of modified bacteria, the production of erythropoietin in Chinese Hamster Ovary cells, and the production of new types of experimental mice such as the OncoMouse (cancer mouse) for research, through genetic redesign.

Genetic engineering can help many disorders that result from genetic misorders and mutations.  The controversy surrounds the use of cloning to produce "identical organisms" where the clone's cells can be used to produce talor made tissue.  I do not believe cloning is necessary to get stem cells to carry out genetic engineering.  THere are sources in the body to retrieve stem cells.  The problem is obtaining cells that have not specialized.  The less specialized the easier to make the cell transform into a specific cell for tissue growth.  Also, all cells contian the same copy of DNA.  I think it is only a matter of time before engineeris can stimulate a cell into changing into another cell.  Other than that there is nothing really controversial about genetic engineering.

The Creator was not such a great genetic engineer, this is clear. He apparently had extreme difficulty making people that are good, and have free will (at the same time). I'm sure this can be done, and in the future even people will make such people. You only need to modify a bit of this...\n\nGATCAATGAGGTGGACACCAGAGGCGGGGACTTGTAAATAACACTGGGCTGTAGGAGTGA\nTGGGGTTCACCTCTAATTCTAAGATGGCTAGATAATGCATCTTTCAGGGTTGTGCTTCTA\nTCTAGAAGGTAGAGCTGTGGTCGTTCAATAAAAGTCCTCAAGAGGTTGGTTAATACGCAT\nGTTTAATAGTACAGTATGGTGACTATAGTCAACAATAATTTATTGTACATTTTTAAATAG\nHuman Genome: First 4 lines of Chromosome 1 \n\n...(actually not those lines but a bit later in the code), and bingo, you got it!

The use of microorganisms, such as bacteria or yeasts, or biological substances, such as enzymes, to perform specific industrial or manufacturing processes. Applications include the production of certain drugs, synthetic hormones, and bulk foodstuffs as well as the bioconversion of organic waste and the use of genetically altered bacteria in the cleanup of oil spills. \n\nThe application of the principles of engineering and technology to the life sciences; bioengineering. \nSee ergonomics.

~ genetic engineering of food, especially for third world countries, and replacing lost vitamins, minerals, etc.\n~ DNA fingerprinting, DNA polymerase, for crime scene investigations\n~ Scientists are now able to clone virtually anything to improve the desired characteristics. For example, genetically engineered animals like pigs are now being tried out to include omega 3 fatty acids for all those meat lovers. (Pigs have more omega 6 fatty acids originally.)\n~ There are so many more values of genetic engineering. You need to do some research on this. Try looking on the web, or in your school textbook (i.e. Biotechnology Unit). It is a hotly debated topic, so its scope is extremely wide. \nGood luck!!! :)\n\n*ANON*

Where is the genetic revolution headed? Without question, it contains great potential for good in the form of better drugs, better medical care, and improved understanding of how living things work. But there is another side to the revolution.\n\n“We want perfect babies,” says Jeremy Rifkin. “We want perfect plants and animals. We want a better economy. There’s no evil intent here. The road to the Brave New World is paved with good intentions.\n\n“Step-by-step, we are deciding to engineer parts of the genetic code of living things. Two important questions emerge: If we’re going to engineer the genetic code, what criteria does this society establish for determining good and bad, useful and dysfunctional genes? And I would like to know whether there is an institution anyone here would trust with the ultimate authority to decide the genetic blueprints for a living thing?”\n\nThese are questions that deserve answers. Who is better equipped than the Creator of DNA to determine what is a good or a bad gene? He is the one who knows the innermost workings of the genetic code, as is shown by David at Psalm 139:13-16: “You kept me screened off in the belly of my mother. I shall laud you because in a fear-inspiring way I am wonderfully made. Your works are wonderful, as my soul is very well aware. My bones were not hidden from you when I was made in secret, when I was woven in the lowest parts of the earth. Your eyes saw even the embryo of me, and in your book all its parts were down in writing, as regards the days when they were formed and there was not yet one among them.” Would you not prefer to trust Him with the ultimate authority to decide the genetic blueprints for all living things?\n\nFor more info visit http://watchtower.org

Biotechnology is a subject that involves the understanding of the physiology, functions and activities etc of various Biological entities and the use of technology in it to produce better products. \nThe main branches of bio tech are plant bio tech, animal bio tech, genetics, Environmental bio tech, Etc. Each of these branches involves the development of that particular branch with the use of technology.\nMedicines or the medical aspect of biotechnology is found in most of these courses. But the basics has to be genetics if you mean to study human disorders etc.\nBiotechnology has a good future as biotech products are now in demand. Also biotechnologists are needed in researches, Pharmaceutical companies, And various biotech companies itself.

There is not a lot of information out there on GE foods. Some of the testing has been stopped because the results were not what the GE companies wanted. You could start by looking at "Seeds of Deception" by Jeffery M Smith.(copywrite 2003) It does not talk about fruits specifically, but does discuss some potential effects of genetic engineering. There is also an extensive bibliography with some references from 2002.

The primary function of DNA in most organisms is protein synthesis. DNA holds the "blueprint" for every protein necessary to sustain life. \n\nThe combination of a certain gene's base pairs is transcribed into messenger RNA (or mRNA). That mRNA is then carried to the ribosome where, with the help of transfer RNA (or tRNA) amino acids are assembled in a particular order to form proteins. And proteins are essential in just about every step of the life functions of an organism. \n\nIt's these proteins that make your eyes blue, your hair brown or give you no hair at all. In fact, all genetic traits are expressed through proteins created using the DNA blueprint. People look different and have different characteristics due to variances in the types of proteins and combinations their genes code for.

OK people...here's the lesson for the day...this is an actual bonified case of a genetic trait that is actually inherited through birth....you will notice that it's not some sort of sickness or illness that we all like to pass off as genetic, but it's an actual physiological trait that can be attributed to a genealogical factor...ooooooohhh...amazing isn't it?.......it's just  pigmentation...nothing to worry about...actually kind of unique and cool...a genetic trait stamp like a birthmark, high intelligence or big feet etc...this is what we inherit genetically from our lineage...v cool...

Biotechnology covers a wide range of uses, but I'd say that mostly it's about manipulating cells to express genes that we want them to express.  This could be to make them produce industrial enzymes, designer agriculture, or biopharmaceuticals.  the genetic code is pretty much universal, meaning we can take a gene from one organiand put into another to acheive specific results.  Industrial enzymes can be used for anything from cleaning wastewater with special enzymes to degrade certain toxins, to making enzymes that breakdown starch into sugar for the production of ethanol for fuel, to the making of specific detergents.  With agriculture, we can transfect plants with genes that make them more resistant to diseases or vermin, or more robust and able to grow under more varied claimates, or we can make food bigger or more nutritious.  In biopharmceuticals, we address genetic disorders by creating the proteins that some people are unable to make for themselves, allowing them to lead more normal lives.

Hi Genetic engineering is done with a purpose, for making human insulin by the use of bacteria for instance. Genetic modification can be caused by an errant cosmic ray.

The function of DNA is to allow an organism or cell to synthesize proteins and to pass that cell's/organism's characteristic to future generations of both cells (mitosis) and offspring (meiosis) \n\nIn protein synthesis, the vast DNA base pair sequence contains the blueprints for every protein produced by the body.  Through transcription of certain genes by RNA polymerase a strand of mRNA is produced.  This mRNA then exits the nucleus and enters the ribosome.  There, with the help of tRNA, the ribosome "reads" the mRNA and constructs a chain of amino acids until a complete protein is produced.  \n\nIn order to make sure future cells have the exact genetic makeup of parent cells, DNA Polymerase unzips the double helix and makes an identical copy of the entire DNA sequence.  During mitosis, these identical chromatids separate, and the cell divides into two daughter cells with identical DNA.

THAT PRETTY LAME IF YOU ASK ME.GENETICS AND GENES AND CHROMOSONES ARE THE CONSTANT ENVIRONMENTMENTALLY UNFRIENDLY OR MAYBE FRIENDLY COMPONETS THAT DESIGN A HUMAN BABY. HOW THE CHILD WILL APPEAR LIKE HAIR COLOR SEX EYE COLOR AND IF THEY CAN HEAR OR SEE ARE ALL GENETICALLY INSPIRED.IF YOUR A MALE TAKE A LOOK AT YOU OWN MOM AND HER DAD.IF YIUR FEMALE LOOK AT YOUR DAD AND HIS MOM.DNA WILL DEFINITELY GIVE YO AND IDEA WHAT YOU WILL APPEAR WHEN YOUR OLDER.

biotechnology is seen by many as one of the most advanced form of technology.according to me biotechnology is engineering for the animals.it is a blend of biology and chemistry that is used to cure, incurable diseases just by correcting the very genes or cells that cause the disease.an engineer aspiring to become a doctor can make a great biotechnologist.

mRNA is essentially the "working copy" that gets actually used to guide protein synthesis.  It's like keeping a master schedule on your computer.  You wouldn't have everyone consult your computer to see the schedule, you'd print them a copy, and keep the schedule safe on your computer.\n\nThe other purpose of mRNA is to control protein expression.  You've got your one set of DNA, with (for most genes) one copy of every gene your body needs.  But any given cell wants to express only certain proteins, and how much of a certain protein is wanted depends on the cell type, and wha't going on in the life of the cell.\n\nSo if a cell wants lots of a gene product, it makes lots of mRNA.  And if it doesn't want to express a gene at all, it makes none.

My opinion is that it is messing with things that we don't understand.\nNobody really knows how life works, or how procreation really takes place.\nBy messing around we are destroying natural evolution, and creating potential situations for the spread of incurable disease.\nAny of the pros can be examined, and the question 'Why?' asked.\nThere is almost always a logical answer.\nWhy do we need more food? Because the nutrition of present food has been destroyed by the fore-runner of genetic engineering - unnatural farming in order to make more profit.\nAlmost always there is an answer which ends up with - to make more profit.\nOur current society is run on the idea that profit is essential. If we examined all these things down to the root we would see that society is definitely headed in the wrong direction, and genetic engineering is a part of that.\nIt's of no long term benefit to the human race.
