What is genetic engineering?
genetic engineering is the use of various methods to manipulate deoxyribonucleic acid (DNA) cells to produce biological products or to change hereditary properties. The techniques used include the use of needles for inserting the bottom into the egg, hybridomas (hybrids of cancer cells and cells that create the desired antibody), and a recombinant DNA in which the DNA of the desired gene is inserted into the DNA bacteria. The bacteria is then reproduced and provides more desired gene. Another type is the polymerase chain reaction (PCR), which recommends a laboratory process in which a particular DNA segment is quickly replicated to create a large, easy -to -analyze sample. This process creates a perfect copy of DNA fragments and is used in fingerprints .
The human genome project, an ambitious attempt to map each human gene was completed in 2003. Armed with these information, scientists hope to treat and treat many types of chronic diseases such as cancer, diabeT, Huntington, Huntington, Huntingtono and Neurofibromatosis (Human Elephant disease.)
Many genetically modified products are already on the market. Belongs to this Bacteria designed to spend oil angles and industrial waste products, growth hormones for humans and krava, medicines such as interferon and insulin, and plants that are resistant to insects and diseases.
genetic engineering techniques were also used in changing livestock and laboratory animals. The most famous of these animals was Dolly, the first cloned sheep. Genetically modified products require approval of at least one US government agency, such as food and drug management or environmental protection agency.
The first genetically modified pet was sold in 2003, when scientists put the jellyfish gene into the normal zebrafish to shine yellow -green in the dark. “Frankenfish” was expected to be a big item but PROdej was flat.
Many people question both ethics and the safety of genetic engineering. Because science is so new, there is no way to predict potential consequences for human health and safety if the genetically modified animal escapes the laboratory or if the genetically changed food should prove to be unexpected consequences. Several cases of genetically changed wheat infecting normal wheat crops have been reported. Infected crops were destroyed.
