Telomerase

Uncontrollable Growth of Cancer Various risks factors can contribute to the development of cancer, but the cause of this rampant disease is uncontrolled cell growth. Cancerous cells divide without limit because of the production of the enzyme telomerase that speeds up the process of cell division. Cancer cells derive from mutation in genetic DNA, and becomes carcinogenic cells that renew themselves indefinitely. When this fatal continuous process occurs, it results in a tumor. Although…

HeLa cells are cancer cells that come from a human’s cervix. These cells were the first of human cancer cells to be continuously cultured and led to many other strains of cells that could also be used for experimentation. When a cell is cultured that means that the cell is removed from an animal or plant and instead grown in an artificial environment. These cells were important to study because they grow extremely fast if they have the right conditions and enough space. Most cancer cells do…

Magnesium stabilizes DNA. It also is related to the function of telomerase. Telomerase elongates telomeres in the body. Elongate telomeres have been associated with reduced aging. Therefore, magnesium can also slow down the aging process (Rowe). Magnesium activates enzymes and it regulates many of the nutrients that are in…

In the Hallmarks of cancer, the cancer cells are that which, when in the body, tries to avoid being killed off (apoptosis). Once a cell does happen to die, the cell membrane shrinks down and the cell to the next of it will devour the rest of the pre existing cell. When a cancer cell that make up a tumor needs to grow large, the tumor then depends on the blood vessels to nourish upon. The tumor rely on the nutrients as such; oxygen, glucose, and amino acids. The waste that expels out of the cell…

in research regarding the regulation of in vivo stem cells in an attempt to better understand how all animals’ stem cells function (Reddien et al., 2005). Furthermore, they are also involved in anti-aging studies because of their non-shortening telomerase (Tan et al.,…

telomeres. As soon as the telomeres run out, a cell is stopped. But with telomerase, cancer cells can add on to telomeres repeatedly, meaning the telomeres don’t run out. Telomeres are replenished so quickly that the Hayflick limit never has the chance to start, the cell’s DNA is protected by an everlasting set of telomeres. Scientists are working to finish a test that will immediately trace any signs of increased telomerase activity. This will lead to cancerous cells being discovered more…

In "the Average Life Expectancy Could Soon Reach Above 90 Years Old", by Maria Chang, she discusses how America is falling behind other countries on average life expectancy, despite its wealth. It is shown that countries with more money tend to have longer human life expectancies, because of their ability to afford to maintain a healthy environment. So why is the United States, the ninth richest country falling short in these ranks? "Researchers note that among rich countries, the U.S. has the…

HeLa cells are a unique strain of cancerous cells obtained from the cancerous cervical tissue of Henrietta Lacks, who perished to the disease on October 4, 1951. HeLa cells are unique because they are “immortal”. HeLa cells are immortal because they do not experience programmed cell death like normal cells would, allowing the HeLa cells to replicate infinitely without experiencing degeneration of genetic material. It is suspected that Henrietta's human papilloma virus and syphilis played a…

26. a. Females would be healthier in an area with malaria because they have two X chromosomes. The genetic mutation for favism is only passed on the X chromosomes, so because females have two, this means that in populations where the mutation is widespread, many females have a red blood supply that is half G6PD deficient and half normal. So, this gives females extra protection against malaria, while they also won’t have a dangerous reaction to fava beans. b. People of Mediterranean descent would…

Nuclear Transplantation Cloning Nuclear transplantation cloning is a way of reproducing when one is unwilling or unable to use gametes. A procedure can remove the nucleus from an oocyte and replace it with a nucleus from a somatic cell. Then, a stimulus will cause the egg cell to start replicating. The gestation part is the same as with anyone conceived; one will be gestated for nine months before birth. There are controversial views on cloning, with Kass strongly opposing the idea. One…
