5 Protein adalah bahan kimia super-kompleks dimana perbedaan muatan listrik sedikit saja, atau perubahan pH, bisa memutar posisi atom C atau H sehingga jadilah bahan yang lain sama sekali

6 The Genome Project | The Human Genome Project = Pemetaan Gene Manusia

8 Perjalanan Ilmiah To observe To describe ada chromosome x dan y
ada sifat yang sex-linked ada protein DNA yang salah urut To describe urutan abnormal pada rantai X menyebabkan (misalnya) phenylketonuria

9 Perjalanan Ilmiah To understand To predict To control
kejadian phenylketonuria tidak ada pada ras yang chromosome P-23xx nya lengkap To predict genetic mapping pada fetus, kehamilan diteruskan atau abortus To control merubah DNA agar tercipta mahluk sempurna

10 Tujuan semula Kasihan pada pasien penyakit sukar
Hemofilia, Sickle Cell Disease, Multiple Sclerosis, Leukemia dll Diabetes 10% populasi = milyaran pasien yang menderita Produksi makanan yang kurang banyak orang Afrika mati kelaparan Wabah penyakit virus ganas, parasit, vektor yang sukar diberantas

14 Memproduksi “mahluk baru” sesuai pesanan
Penemuan DNA dan gene Deskripsi peran masing-masing gene Genetic engineering Manipulasi dan intervensi pemotongan dan penggantian gene dan DNA Menciptakan mahluk “baru” Cloning

15 Apa salahnya menciptakan mahluk baru ?

16 The question Apakah mahluk ciptaan manusia ini persis membawa sifat yang kita rencanakan ? Apakah mahluk ini tidak membawa sifat yang tidak kita rencanakan ? Apakah mahluk ini tidak melahirkan sifat dahsyat akibat interaksinya dengan alam sekitar / mahluk lain yang sudah ada ?

17 The answer We don’t know For God’s sake we don’t know
But it is promising financially 91% GMO di dunia buatan Monsanto, USA Bibitnya tidak dapat disemaikan ulang Seluruh dunia tergantung pada beli bibit dari USA dan tergantung planning tanam negara adi kuasa

18 Creatures great and small
Thousands of different GM mice have been created, to "model" human diseases Sheep, cows, mice, pigs, rabbits and cats cloned Dumber farm animals less sensitive to stress and pain making easier for farmers to handle. GM chickens whose eggs contain medicines, Spider goats to produce spider's web in their milk, to make body armour. Killer moths created to pass deadly gene to their wild offspring, which feed on cotton plants.

19 Murphy’s law: If anything can go wrong, it will go wrong

20 Biopharming : genetic tinkering can turn an ordinary- looking corn field into a potential drug factory, producing insulin, chemotherapy drugs, and other products cheaper than it costs to set up factory plant

21 Ini jagung. Apakah cuma jadi makanan sapi ? Atau menghasilkan racun yang akan membuat ganas E.coli dalam usus orang yang memakannya ? Ini padi. Tetapi apakah padi ini hanya menghasilkan beras ? Atau antibiotika dalam skala raksasa ?

22 Ke rumput & gumma Ke jagung lain Ke hewan pemakan Gene transfer

23 Monsanto and Ciba-Geigy produce herbicides
Monsanto and Ciba-Geigy modify genes that make RR soybeans and Max corn resistant to herbicides they produced Those genes could transfer to weeds, making those weeds resistant to herbicides. Such resistance has already been observed in Denmark, where rapeseed, a native European plant used to make vegetable oil, was genetically altered to resist a pesticide. That resistance then jumped from the rapeseed plant to neighboring weeds Genes can destroy native plants permanently

24 GM genes found in human gut John Vidal, The Guardian July 17, 2002
British scientific researchers in Newcastle University have demonstrated that genetically modified DNA material from crops is finding its way into human gut bacteria, raising potentially serious health questions. People's resistance to widely used antibiotics could be compromised.

25 GM genes found in human gut
Seven human volunteers had their lower intestine removed in the past and now use colostomy bags. After being fed a meal of a burger containing GM soya and a milkshake, the researchers compared their stools with 12 people with normal stomachs. "a relatively large proportion of genetically modified DNA survived the passage through the small bowel".

26 GM DNA might be transferred via bacteria to the intestine
Cultivated bacteria from stools in the colostomy bags showed in three of the seven samples that it had taken up the herbicide-resistant gene from the GM food at a very low level. Michael Antonio, a senior lecturer in molecular genetics at King's College Medical School, London, said "To my knowledge they have demonstrated clearly that you can get GM plant DNA in the gut bacteria”

27 European scientists are worried about a bacterium gene in Ciba-Geigy's corn that conveys resistance to the antibiotic ampicillin. The gene could be passed to the cattle who eat the corn then spread to people who eat the cattle. Both animals and humans would then become resistant to ampicillin

28 Monsanto Artificial bovine growth hormone (rBGH) 1994 :
the drug increased milk production but the resultant health problems in cattle outweighed the benefits from the extra milk produced. Sales drop 55% in 2 years. Flavr Savr tomato is genetically engineered to taste like a homegrown tomato yet be sturdy enough to ship across country. Bollgard, genetically engineered cotton, produce a natural pesticide to three insects that eat cotton. Bollgard failed to perform as expected during a heavy bollworm infestation. Monsanto began telling farmers that spraying might be necessary to save their crops.

29 Monsanto, Abbott dll In theory, Bollgard cotton works because it has been genetically engineered to contain genes from the bacterium Bacillus thuringiensis (Bt), which is harmless to humans but in high enough doses kills insects. The long-term implications are frightening. Bt, a natural substance. Making this natural pesticide an integral part of cotton and soybeans and corn, will hasten the evolution of Bt-resistant insects. Abbott Laboratories marketed DiPel insecticide, a blend of five or more toxins as the solution for growers who planted Monsanto's Bollgard.

30 Monsanto, Ciba-Geigy Ciba-Geigy has similar plans for Maximizer, a corn hybrid loaded with three altered genes. Like Monsanto's cotton, Ciba-Geigy's corn contains a Bt gene that makes the corn toxic to pests, in this case the corn-borer larvae. Like Roundup Ready, Maximizer is also built to resist one of Ciba- Geigy's herbicides, glufosinate

31 The EPA announced that Pioneer Hi-Bred Int, Inc
The EPA announced that Pioneer Hi-Bred Int, Inc. (Des Moines, Iowa), had paid a $72,000 fine. The penalty was imposed after the company had failed to promptly report test data showing that a gene engineered to protect against corn rootworm had contaminated other experimental plants in an adjacent field at the company's research facility in Kauai, Hawaii.

32 Bagaimana jika gene ini masuk ke sel manusia dan masuk ke DNA nya ?
Pada orang sakit berat dengan terapi recombinant products ? Pada bayi dan anak tumbuh kembang dengan diet susu atau makanan tambahan Genetic Modified ?

33 10 processed foods that will soon contain Roundup Ready soybeans and Maximizer corn

48 The answer We don’t know

49 (Surat Huud : 85) Dan (Syu’aib) berkata :
“Hai kaumku, cukupkanlah sukatan dan timbangan dengan adil dan janganlah kamu kurangi sedikitpun hak-hak manusia, dan janganlah kamu berbuat bencana di muka bumi sebagai orang-orang perusak. (Surat Huud : 85)
