Afrika ndo mahali pazuri pa kufanyia majaribio haya. Madhara yake ya kiafya hayajulikani ila tusishangae kansa mbalimbali zikianza kututeketeza [emoji36][emoji36]

What’s a GMO
Genetically Modified Organisms (GMOs) are those plants, animals or microorganisms, in which the genetic material (deoxyribonucleic acid or DNA) is altered in a way that does not occur naturally by mating or through natural recombination. They are produced using genetic engineering technology, also known as recombinant DNA technology, in which scientists transfer select genes from one organism into another of the same species or a non-related species so that the recipient acquires a desired trait. So far, the major use of the technology has been to make crops resistant to pest attacks, improve their tolerance to herbicides and to increase their nutritional content. For instance, scientists have developed Bt variants of cotton, corn and soyabean by inserting the gene of a bacteria, Bacillus thuringiensis (Bt), into the plants’ original genetic material. BT gene expresses codes for Bt toxin protein, which when ingested by bollworm insects attacks their gut cells and kills them. Similarly, scientists have developed herbicide-tolerant (Ht) corn, soyabean, cotton and rapeseed by modifying the gene that produces the enzyme EPSPS (5-enolpyruvylshikimate-3-phosphate synthase) in plants. The enzyme produced by the modified gene does not get degraded by herbicides like glyphosate and glufosinate, and therefore does not harm the plant. While there is no clear evidence of these claimed benefits outside confined laboratories, studies do indicate their impact on human health.
