Some examples of biotechnology include human gene therapy, genetically modifying plants and changing the genes of bacteria. Biotechnology helps improve crops so they produce more, healthier produce. It also helps fight human diseases.Know More
Biotechnology is generally involved in changing the genes of a an organism to get the desired result. It affects the most people through genetically modified crops. Genetic modification of crops started thousands of years ago through selective breeding for preferred traits, but with the advances in technology in the modern day, scientists are able to directly manipulate genes. These plants produce higher quality food at a higher rate, and are often resistant to pests and diseases, which helps feed larger amounts of people for a lower price on less land.
Biotechnology more directly helps humans with gene therapy and the modification of bacteria to produce insulin for patients with diabetes. Gene therapy can help reduce or remove the effects of a disease, such as cancer or AIDS, but is still mostly in research and development. This type of therapy is still promising and has had good results in testing phases. Modified bacteria cells that produce insulin as they age helps treat and control the effects of diabetes in humans over time.Learn More
One biotechnology topic is the genetic modification of crops. There are also a variety of biotech companies that are coming out with treatments for patients dealing with major illnesses such as breast cancer. There are even attempts to develop new drugs to save the lives of pets.Full Answer >
The benefits of using biotechnology to genetically modify organisms include increased yield at reduced cost, lower prices, increased land use, reduced use of pesticides, and increased profits for companies that develop the plants. The objections to this technology include a fear of playing God, fears about whether genetically modified crops are sustainable and worries about the distribution of benefits and burdens.Full Answer >
Mitosis occurs in almost all cells in plants and animals. It begins in the nucleus of the cell. As neurons become specialized (terminal differentiation) mitosis is switched off, so the cells can no longer reproduce.Full Answer >
Plants and animals are both multicellular eukaryotes. Along with fungi, they are the only organisms in the world that are capable of building large bodies. Unlike most fungi, plants and animals have differentiated tissues that develop into discrete organs.Full Answer >
