Research Technologies Uses for Medical Imaging In Canada (X-Rays, Ultrasound, CT Scans, MRI, Microscopy)
Genetic Engineering has been around for many years. With Genetic Engineering, you never truly know what can go wrong inside either your body or in plants. Therefore, scientist have used a variety of medical technologies to help diagnosis and treat anything that goes wrong. Monoclonal antibodies, microscopy are two of the many examples on ways to diagnose the effects of Genetic Engineering. Monoclonal antibodies are when an antibody is produced by a single clone of cells. Monoclonal antibodies can be used to treat many diseases. However, the most effective method to diagnose any disease created by genetic engineering is the use of microscopes. An expert can look at cell or tissue samples under a microscope to determine whether there is an abnormality in the cells. The results from the microscopy, is then used to choose the best treatment (Usually removing the cells of the disease or the use of radiation).

Without the medical advances used in our world today, most diseases would not be curable. For instance, let's look at cancer patients. Doctors often protect patients, and give them antibiotics immediately after treatment. If those antibiotics weren't created or made, we get to the stage where we would have no suitable antibiotics. Doctors couldn’t knowingly give a patient chemotherapy that will destroy their immune system, when they don’t have anything to save them from subsequent infections. Famous German chemist Paul Ehrlich set about developing drugs to treat infectious diseases. He created the term “chemotherapy” and defined it as the use of chemicals to treat disease. Without the development of chemotherapy there would be no way of treating and helping the victims of the frightful diseases.

Genetic Engineering is used in both plants and animals all over the world. Cells of an organism are being altered and/or replaced to change an external or internal feature. That being said, cells in the organism may not know how to react to the cells being formed or replaced in their environment. This procedure may provoke the surroundings of the cell in the formation of a new frightful disease. After all, that may not always be the case. Genetic Engineering is also benefiting others and is helping to cure certain diseases like HIV, Hemophilia and Familial hypercholesterolemia. Genetic engineering helps by replacing the contaminated cells with the cells or DNA from another organism. Genetic Engineering can further be used to change the physical features of an living organism as well. Things like altering the colour of your eyes, and the even the colour of your hair.

Public health programs are an organized way that offers the benefiting needs to a large population of people, including those who are identified as high risk, early treatment, and/or reproductive options. Some examples of health programs related to genetic engineering would be preimplantation genetic diagnosis (PGD). PGD allows couples to ensure their offspring are unaffected by any diseases. This could end to the parents making a horrific decision regarding termination during pregnancy. For example, some parents might choose to undergo embryo screening to see the male/female embryos. By doing so, they can either decide if they want a girl or a boy by having more of a particular embryo (male/female depending on their choice)
Solution to One Of its Problem
After looking at the problems genetic engineering creates, genetically modified foods is one of the main concerns. Genetically modified foods create the problems of: Creating new allergies/toxins, and Harm to the animals that consume them. However, these problems could be solved with two alternatives: crop breeding and agroecological farm management. Crop breeding consists of modifying the crops reproductive process to add/remove traits to benefit the society as a whole. As for agroecological farm management, it consists of practices that work with nature to avoid damaging the area like industrial agriculture (farms/ranches). Studies have proven that agro-ecological farm management can help benefit the world with losing any productivity or profitability. These solutions are less expensive than genetic modification and sometimes more effective. Although these alternatives are great solutions, industrial agriculture can ensure the products, seeds, and methods will continue to control the markets
Brief Lesson of Our Unit: Mitosis
The major purpose of mitosis is for growth and to replace worn out cells. During mitosis one cell divides to form two identical cells called daughter cells. Mitosis consists of 4 different stages: Prophase, Metaphase, Anaphase, Telophase, but there is also another stage called cytokinesis (When the 2 daughter cells are formed). Prophase is when long strands of the DNA condense to form visible chromosomes. During prophase, the nuclear membrane breaks down as well. Next comes metaphase. Metaphase is when the chromosomes line up in the middle of the cell on spindle fibre tracks. Then comes Anaphase, which is the separation of the chromosomes and sister chromatids. Finally comes Telophase. Telophase is the final stage of mitosis and is where new nuclear membrane forms around eat set of daughter chromosomes and the 2 cells also appear to have two nuclei. These are the 4 stages in which cells are divided into 2 identical cells called daughter cells.
