In contrast, if the promoter is not functioning correctly, it could cause cell division too often thus causing the same effects as cancer. There are many steps to fixing a gene, scientists cannot move on to step two until they have successfully completed step one. Among these technical holdups, research in biotechnology has run into serious problems. In his article titled “Human Gene Therapy: Harsh Lessons, High Hopes”, Larry Thompson, tells of more setbacks the industry has come upon.
Aging cells are more susceptible to an increase in cellular damage, which can lead to abnormal cell function. As a result, cell division and replication occurs at a slower rate or may not occur at all in some cells. All cells con... ... middle of paper ... ...inated through urine. In men, it can cause erectile dysfunction or vaginal dryness in women. The natural process of aging is inevitable and we cannot escape it.
The consequences of cloning these vital organs, cells, and tissues would be that many things could go wrong during the cloning process, especially due to the fact that the technology isn’t completely developed properly yet. Because the patients are already ill, they are more likely to suffer from any type of glitch in the process. Therefore, the main consequence is that if something were to go wrong, their chances of not living would be increased, also. Despite this possibility, researchers and scientists are continuing their studies by making huge efforts towards the cloning of humans and cells. They are doing so in order to take strides towards making what they believe would be a big difference in medicine for the present.
This would bring about a lot of confusion and emotional damage for the individual. There is a great margin of error in the new technology of cloning. Because we are still developing these scientific procedures, there is a lot of room for mistakes. This means that in the process of experimenting, clones with great genetic abnormalities could be created. What would happen to these degenerate individuals?
In face, this cell division process is a highly ordered process. This is a critical issue in cancer, because cancer cells do not obey or require normal signals for division. This could lead to the formation of mass of cells that piles up that may form a tumor. Also different from nomad cells is the ability of cancer cells to divide indefinitely. A important point about cells is that no matter what their job is in a body, they all have the same general structure that they all have different kinds of organelles that play different important functions for the cell.
This memory loss is slowly joined with forgetfulness, cluelessness of hygiene, impaired judgement, and loss of concentration. The later symptoms... ... middle of paper ... ...new treatments and earlier diagnostic. Alzheimer’s Disease is the most common form of dementia, yet there is no cure. As the disease progresses, patients get worse and worse until death. This disease is caused by a buildup of amyloid plaques and neurofibrillary tangles in the brain, which do not let the brain function properly.
This process of cell change is called somatic mutation. Although not all of the blood cells will have this faulty gene the ones that do will only be able to produce more mutated cells creating a cycle of increasing damaged cells that keeps expanding. The number of mutated cells a person with this disease has is what determines the degree to which they will suffer from the symptoms. As the number of PNH cells increases so does the symptoms. The PIG-A gene also plays a part in sending the signals to the body on how to make GPI anchors that secure compliment regulating proteins to blood cell membranes.
Abstract Sickle Cell Anemia is a hereditary disease that changes the smallest and most important components of the body. A gene causes the bone marrow in the body to make sickled shapes, when this happens; it causes the red blood cell to die faster. This is what causes Hemolytic Anemia. Older children and adults with sickle cell disease may experience a few complications, or have a pattern of ongoing problems that shorten their lives. The most common and serious complications of sickle cell disease are anemia, pain, fatigue, and organ failure.
The optimist foresees a time when a patient will simply receive a snippet of DNA and go home cured. There are many ethical and scientific hurdles that must first be crossed for such a dream to become reality. The technology has advanced so rapidly that many ethical questions weren’t originally addressed and accordingly are now becoming the center of attention regarding human genetic research. Furthermore, scientists must find a way to outwit the body’s immune system which is primed to fight any foreign material such as inserted genes. There are also difficulties in getting the targeted cells to open up their molecular locks to allow the foreign genes inside.
It is a journey to the maturity, as well as to the degeneration of the body. Because aging affects every part of the body, many different steps are involved and various types of reactions occur. Changes in DNA take place, which can and often do affect the way the body functions; harmful genes are sometimes activated, and necessary ones deactivated. A decrease in important body proteins like hormones and certain types of body cells is almost inevitable. These, among many, are characteristic changes that take place in our bodies as time moves on and aging continues.
