Telomere

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. In these types of animals the parent dies off after the egg is fertilized and laid. This theory only works if all of the requirements…

Bowhead whales are not the only large animals that are known to resist disease. One would think that because larger animals have more cells they would be more susceptible to mutations. One would also think that the more time an animal lives, the more time it has to develop mutations. This is not the case and this lack of correlation is called Peto’s Paradox (Caulin & Maley, 2011, p. 1). The statements mentioned above are incorrect because it is known that some larger animals live longer. Much…

claim by conducting an experiment in which premature infants are stimulated with music to observe how the music affects their issues cause by prematurity. “ Written by Vimal Vasu and others, the article “Preterm Infants Have Significantly Longer Telomeres Than Their Term Born…

with respect to lifespan therefore this must be a strong biological aspect to a species maximum life span. One speculation is the telomere length in chromosomes plays a role in the life span of Homo sapiens and other species of animals. For instance, shorter telomere correlate with a shorter life span. Each time a chromosome divides and makes a new cell, the telomeres decrease…

34. The Hayflick limit is the limit to the amount of times cells divide for cellular reproduction. For humans, the limit to the number of divisions is between 52 and 60, but varies depending on the organism. The limit is related to the loss of telomeres, which are buffers that sit at the end of…

With it being the size of a walnut, the prostate gland is found between the bladder and the penis, and is part of the male reproductive system. There are three main disease associated with the prostate, including prostatitis, benign prostatic hyperplasia, and prostate caner. “Prostate cancer is an aggressive growth of malignant cancerous cells in the prostate that can be fatal.”(Cramer, 2015) In addition, prostate cancer is one of the most prevalent cancers in men and is one of the leading…

discover the existence of telomere in 1938. He was irradiating Drosophila melanogaster with X-ray to produce mutation at the Drosophila’s chromosomal ends and he observed no mutants with deletions or inversions during the experiment (Muller, 1938). He suggested the presence of a protective cap, known as telomere, at the chromosomal end. It wasn’t a year later; Barbara McClintock - a cytogeneticist from the University of Cornell - proposed another main function of telomeres. While investigating…

programming can cause the embryo to develop abnormally, or even fail entirely. Lastly, another defect occurs in the telomeres of the cells. As cells divide, their chromosomes get shorter. Telomeres, which are the DNA sequences at both ends of a chromosome, shrink in length each time DNA is copied. The older the animal, the shorter the telomeres. Clones cells have longer telomeres than their normal counterparts. Clones cells show other signs of youth and appear to have an extended lifespan…

more insight into macromolecule density and distribution, as well as provide answers to the still unknown mechanism involved in spatial compartmentalization. Moreover, research on the role of CDK-1 has revealed that it is an important component in telomere/nuclear envelope separation [3], and therefore important in spatial organization and gene expression.…

documentary I saw about the genes of fruit flies when I was younger mentioned that the burning of the telomeres due to stressors was the reason for aging. Since then I've looked into medical journals trying to understand different theories for aging and what was being done to try to stop it. My first idea was just to simply cap the telomeres to prevent outside stressors from affecting the telomeres. However, how would…
