Pages 3
The difference between the cell cycles of a normal and cancerous cell is that the cancerous cell is uncontrolled when it reaches the cell division or anything else goes wrong threwout the cycle(can be very dangerous) and the normal cell is controlled throughout the whole cycle. In the g1 phase, the cell synthesizes mRNA and proteins in preparation for subsequent steps leading to mitosis. When the cell reaches the end of the G1 phase it is controlled at a checkpoint called G1/S, G1/S is when the cell decides whether or not to replicate its DNA. At the checkpoint the cell is checked for DNA. Cells with no damaged DNA (normal cells) continue to S phase, in S phase cells with damaged DNA (cancerous cells) that cannot be repaired die. G2 is when cell is about to divide. the M is …show more content…
But when the proto oncogenes are mutated they become oncogenes, oncogenes can cause a cell to become cancerous. DNA repair genes repais genes, and codes for proteins which repair dna pronto of cell division. The 3 genes come in play when the genes detect a damaged or cancerous cell and the genes send messages alerting all the other genes. The genes are a HUGE diagnose of cancer because all the genes were made just for the purpose of eliminating cancerous cells and they can handle damaged cells either by killing them or repairing them, if these genes did not exist then mostly everyone would have cancer because the cancerous and damaged genes will just keep on flowing through the the body with any genes stopping them or fixing the problem. The risk of getting cancer of getting through genetics are one of the main causes of cancer also If someone smokes or drinks it another big cause of cancer. The way people get cancer through genetics is by having a parents or family members have cancer and if they have cancer they must have cancerous cells or damaged cells, and those cancerous cells can get passed on to another family

In the United States, colon cancer is the second cause of death from cancer only surpass by lung cancer. More women die of colon cancer than breast cancer. Although not many do pay attention to the risk factors and symptoms. One reason may be due to the false assumptions that the only way to get rid of colon cancer is to become a vegetarian. It is important to notify people about the symptoms, risk factors, and how hazardous colon cancer can be, but it is even more important to educate the people on how to maintain a healthy lifestyle. Cancer is a disease in which abnormal cells are separated without any control and are able to enter other tissues. There are over 100 different types of cancers and they are mostly named in the organ or type of cell where they initiate. For instance, cancer that starts in the colon is called "colon cancer". If the cancer is not treated or detected, it could lead to serious illness and even death. There are trillions of body cells in the human body. During the early stages of an individual’s life, the cells split rapidly, which lets an individual develop. Once a person is an adult, the cells only separate to patch-up injuries. When the cells start to separate without control, in a...

...conclusive, and in the case of retrospective studies, have often proved contradictory. 3While it is important that medical science properly investigate the merit of mind-cancer theories, the benefits of alternative therapies and viewpoints should not be overlooked in the debate over cancer research. 4The essay briefly surveys the origins of mind-cancer research and the emergence of the field of psycho-oncology, before addressing contemporary research in the area, in particular, the problem of validating results. It concludes by examining the merits of alternative therapies with regard to patient psychology. 5Before examining the origins of mind-cancer research, the physiology of cancer will be briefly discussed. "Cancer" is a general term used to describe a physiological disorder in which cells in the body begin to reproduce as abnormal cells, forming a mass called a tumour. There are different types of cancers and tumours, and the body utilises the immune system to destroy the cancerous cells. If the tumour is malignant, the immune system stops the cancer cells from moving to other areas of the body. The immune system halts the spread of the cancer cells by the use of cytotoxic T-cells, also known as 6"natural...

Ethics

...Lisa O’Neil Ethics and Genetic Engineering Essay Ethics are part of our everyday decisions, in order to be ethical we need to firstly understand the basis of ethics. The word ‘Ethics’ comes from the greek word ‘ethikos’ which relates to the customary way to behave in society. Ethics is a branch of philosophy dates back to before 367 b.c. Famously in the history of ethics and philosophy were ‘’The Three Wise Greek Men’’ Socrates, Plato and Aristotle. Socrates was a teacher of philosophy and Plato was Socrates student for approximately ten years, and when Socrates died, Aristophanes became Plato's student. Aristotle views were that ‘’ethics is a virtue of happiness, and that the pursuit of virtue is the highest and noblest aim for a human being’’ . Aristotle can be seen as saying ‘’ Nobody would choose to live without friends even if they had everything else they desired ‘’ (quoted from The Puzzle of Ethics- Peter Vardy pg 31). Socrates took a practical view on ethics, he was concerned with ‘’how an individual would live in order to achieve happiness’’. Socrates can be seem as saying; ‘’Think hard enough and you will always find that doing the right thing is best for you ‘’ ( quoted in Peter singers A companion to Ethics, Blackwell p. 125 ). Plato's view was much more in depth and most famously contradicts Socrates work. Plato believes ethics is ‘’ knowledge is the virtue of happiness ‘’ .

Sigmund Freud

...Sigmund Schlomo Freud BRIEF OVERVIEW Although Sigmund Freud was not the first person to formally study psychology, many consider him the most pivotal figure in the development of the field as we know it today. Freud changed the way society has come to think about and treat mental illness. Before Freud, mental illness was thought to result from deterioration or disease of the brain. Freud changed all of this by explicitly rejecting the purely organic or physical explanations of his predecessors. Instead he believed that unconscious motives and drives controlled most behavior. During a career that spanned 58 years, beginning with an earned medical degree in 1881 and continuing to his death in 1939, he developed and repeatedly revised his theory of psychoanalysis. Most of Freud’s theory was developed from contact he had with patients seen in his private practice in Vienna. This type of “clinical” work was a radical departure from the laboratory research that was practiced by most leading psychologists of the day. When Freud first presented his ideas in the 1890s, many of his contemporaries reacted with hostility. In fact, throughout his career, Freud faced enormous opposition to many of his ideas. Those especially controversial included notions about the role of the unconscious in behavior, childhood sexuality, and how the mind was governed (id, ego, and superego). But despite the opposition, Freud eventually attracted a group of followers that included well-known theorists 1856–1939...

...THE B L A C K SWAN The HIGHLY I mpact IM of the PROBABLE Nassim Nicholas Taleb U.S.A. $26.95 Canada $34.95 is a highly improbable event with three principal characteristics: It is unpre­ dictable; it carries a massive impact; and, after the fact, we concoct an explanation that makes it appear less random, and more predictable, than it was. The astonishing success of Google was a black swan; so was 9 / 1 1 . For Nassim Nicholas Taleb, black swans underlie almost everything about our world, from the rise of religions to events in our own personal lives. A BLACK SWAN Why do we not acknowledge the phenomenon of black swans until after they occur? Part of the answer, according to Taleb, is that humans are hardwired to learn specifics when they should be focused on generalities. We concentrate on things we already know and time and time again fail to take into consideration what we don't know. We are, therefore, unable to truly estimate oppor­ tunities, too vulnerable to the impulse to simplify, narrate, and categorize, and not open enough to rewarding those who can imagine the "impossible." For years, Taleb has studied how we fool our­ selves into thinking we know more than we actually do. We restrict our thinking to the irrelevant and inconsequential, while large events continue to surprise us and shape our world. Now, in this reve­ latory book, Taleb explains everything we know about what we don't know. He offers...
