Transgenesis Transgenesis is the process in which an exogeneous gene (transgene) is added to an organism genome, and this results in expression of the gene which can then be passed down to its offspring. I have chosen to research how the Enviropig has been manipulated using transgenic techniques. The transgene inserted into the Enviropigs genome is Escherichia coli K12’s phytase gene, this gene gives the Enviropigs the ability to produce phytase in their salivary glands, and it gets infused in…

will be and with a lower concentration the longer the products will be. Fluorescent dyes are yellow dye that are visible even when highly diluted that used as an absorption indicator. Stem cells are characterized by their ability to self-renew by mitosis while in undifferentiated state. Embryonic stem cells are stem cells derived from the undifferentiated inner mass cells of a human embryo, also due to them being pluripotent, they can differentiate into all derivatives of the ectoderm, endoderm…

Cancer shows repetition in the metastasizing of the cell life cycle throughout the body. Comparing cancer cells to healthy cells shows antisymmetry. The prognosis of each patient is never identical to another cancer patient. Different treatments are used and this shows both repeating and antisymmetry. So, where does the cancer came from? Cancer can develop through genetics or environmental factors which is key when looking into how the disease is formed. The development of cancer is not just…

egg cell (which has not been fertilised) is removed using a sharp pipette. This process in known as enucleation. Next, the nucleus of the donated somatic cell is also removed and transferred into the egg cell. For the cell to then begin division (mitosis), chemicals or electric pulse is applied to stimulate development. Once the cells has divided successfully into a blastocyst, an early stage embryo. The embryo is then placed into the womb of the surrogate mother. From here, the embryo should…

Background: What is Down Syndrome? Down Syndrome is a chromosomal disorder caused by an error in cell division that results in an extra twenty-first chromosome, that causes birth defects of developmental and intellectual delays. The human body is composed of trillions of cells and within the nucleus of each cell are structures called chromosomes (Parks, 2009). About eight million babies are diagnosed with Down Syndrome in the United States with approximately twenty thousand in Western Europe…

College students focus on the content presented to the in their courses like understanding the difference between mitosis and meiosis or what exactly Plato meant in his writings. Rarely do students take the time to step back from their studies and analyze the organization of their classes and how that may affect their performance in the course. It is extremely interesting to get a chance to look back on the courses I have taken and analyze their culture rather than content. I will be looking…

of filamentous hyphae while yeasts are spherical or oval-shaped. Molds are colourful while yeast are colourless. Molds can reproduce through small spores sexually or asexually while yeast reproduce asexually by budding or binary fission through mitosis in which a nucleus is divided into two or more nuclei. Mould can grow on food with low pH and low water activities that would normally inhibit growth of yeast which will cause a greater risk in terms of food spoilage and are harmful to our…

Cancer Medicine (Oncology) Cancer cells arise from different normal cells, thus when the normal cells become abnormal, it allows the cancer cells to grow out of control. Cancers can start almost anywhere in the human body, it can occur in any tissue and at any time of life, but mostly, elders have the highest risk. Cancers are called neoplasm because neoplasm is new growths that arise from normal tissue. Furthermore, there are two different characteristics of neoplasm: benign and…

In recent years the field of virology has seen substantial growth as virus have now become a more widely researched subject. It was not too long ago relatively speaking that viruses were more or less an unknown entity, as many facts about viruses were unknown to the days researchers. Now however much more is known about what viruses are and how they work; more importantly it is known that viral agents are one of the leading causes of disease. Once it was established that they did in fact…

1. Detail the first part of the digestive system from the mouth to the esophagus including the structure and functions of each part. The first part of the digestive system is comprised of the mouth, the pharynx and the esophagus. The mouth is an oral cavity that starts the process of mechanical and chemical digestions when food is received. The mouth is bounded by the cheeks and lips. The mouth contains a soft and hard palate, salivary glands, teeth (crown and dentin) and the tongue (covered…
