Theories Of Aging: Wear And Tear And Somatic Mutation

Decent Essays
I selected the following two theories of aging; Wear and Tear and the Somatic Mutation.
I support the Wear and Tear theory for on the surface it makes logical sense to me. If your hard on your body i.e. wearing it down or doing things like substance or alcohol abuse your tearing it down and eventually your body can’t take the beating any longer and will just be worn out and start to shut down eventually leading to ageing and then death.
The reason I found Somatic Mutation interesting and supported it was if your making thousands of copies of something eventually something is not going to copy correctly i.e. a mutation. You get to many bad copies or mutations and the good cells are then outnumbered and can’t keep up with the number of mutation

    . Why does (or doesn’t) the frequency of a physical trait change in a rabbit population in different environments? c. This is an important investigation as understanding how populations are affected by different traits helps to understand why certain species thrive in an a certain an environment and why others don’t. This is an interesting investigation as there are no predators in this investigation, the rabbits are competing for food and that is why they are dying at an alarming rate.…

    Telomeres In Aging Summary

    • 1056 Words
    • 5 Pages

    Oxidative stress, glycation, telomere shortening, and chronological age along with various genes all work together to cause these alterations. Telomeres are the timekeepers of cells. When looking at a group of individuals over the age of 60, it was seen that those who were three times more likely to die from heart disease and eight time from likely to die from infectious disease had shorter telomeres. One of the theories of how telomeres are getting this short is the “oxidative stress” theory. This is where reactive oxygen species are said to cause aging by attacking DNA, causing chromosomal instability, and inducing telomere shortening.…

    Changes in Tissue Homeostasis of the Elderly That Result in Altered Cognitive; Motor Abilities. As we age, homeostasis is harder to achieve within all of our cells. The cardiac muscle tissue and the walls of the blood vessels thicken, decreasing the amount of oxygen and nutrients that is pumped out to the entire body. The thickness of the blood vessels makes it hard for nutrients to enter the other tissues body, and for wastes to leave these tissues.…

    The scientific definition of aging is the deterioration over time resulting in physiological changes. Many evolutionary biologists believe that aging has nothing to do with genetics (Arking). Once, an animal serves its purpose it is able to die off. The purpose being to produce and raise offspring (Gilbert). This happens with many organisms like moths and salmon.…

    If there were to be a mutation, the checkpoints could destroy the cell. However, like most things, there are a few cells thaat contain mutations that pass through the checkpoints. The cells who pass through and reproduce uncontrolably are called cancer. Cancer cells crowd out healthy cells making it harder to or unable to function. An eye cancer, for example, may result in the loss of vision in the affected eye.…

    Epigenetics is the study of how changes and environmental factors experienced by an organism can affect the way genes are expressed without altering the genetic code. Epigenetics has also been linked to ageing. The reason why epigenetics affects ageing is because the DNA methylation acts as a clamp on the chromosomes, so when it comes time for the cell to replicate and unwind its chromatin from around the histones to copy the DNA, the methylation groups don’t allow that segment of DNA from being unwound. Therefore those nucleotide pairs aren’t read and the gene isn’t expressed. Interestingly DNA methylation is inherited through the germline due to a DNA methyltransferase called DNMT1, which copies methylation onto the daughter strand of DNA…

    Searching for ways to reverse the aging process is not a new quest, by any means (Haber, 9). Before the nineteenth century, “… this search was linked to the belief that old age was characterized by a significant decline in vital energy” (Haber, 9). Luigi Cornaro was an Italian nobleman and author of The Art of Living Long, written in 1550, who challenged this belief (Haber, 9). Cornaro’s work became known as “the bible of prolongevity advocates,” as he argued that “… individuals were not destined to die at 60 or 70, but rather, with care and a good constitution, could live much longer”…

Its mission is extensive: “to help older people maintain maximum independence in their homes and communities and to promote a continuum of care for the vulnerable elderly” (nhpf, 2012). Aging is an uncontrollable process in life. It is defined as the process of getting old and the population that is affected is those who are 65 and older.…

    The “aging-out process is the tendency for youths to reduce the frequency of their offending behavior as they age” (Siegel Pg. 49). One of the biggest reasons I feel juveniles “age-out” of crime would be an increase in responsibility. This may not be valid for every individual, but with age comes an increased sense of responsibility. From family, work, school and friends, there are people that are counting on that individual to be a responsible, law abiding citizen within their respective communities. “As youths grow older, they take on new responsibilities that are inconsistent with criminality.…

    The structure of the brain is constantly changing from birth throughout the lifetime. It states that as our brain ages we start to lose our memory, retrieve new information etc. Also, people usually who are above age sixty an experience in cognitive decline, for example: weaken memory loss, decision making, social skills, remembering, paying attention, problem solving, and unclear thoughts. The experience of cognitive and memory loss as aging affects our daily routine and can impact out personality. 2/3 of people will eventually experience a significant loss of mental strength and understanding capabilities because of aging.…
