Biology: Determining the Lengths of Telomeres Using Flow FISH Method

- Flow FISH is a method for determining the lengths of telomeres which is common nowadays due to its versatility, its more rapid and its able to process samples which contain few cells (Lansdorp,1996). The major limitation of flow-FISH is the requirement of the equipment to do the analysis which is expensive, the configuration of the equipment (flow cytometer) and the nature of the probe used for hybridization is also expensive and requires a well trained personnel. Flow-FISH involves hybridisation of telomeric DNA of fixed sample cells with a fluorescently labeled peptide-nucleotide probe with sequence which is complementary to the telomere repeat DNA sequences....   [tags: dna sequence, rna]

Overview of Diabetes

- Description of the disease Diabetes is known to be a heterogeneous disorder which has characteristics of persistent hyperglycemia. There are two major types of diabetes that include type 1 diabetes previously referred to as insulin-dependent diabetes and type 2 diabetes previously referred to as non insulin-dependent diabetes.

Cell Migration

- Introduction Cell motility is currently one of the “hottest” areas in biology. An example of normal healthy migration is in adult skin, when cells migrate from the inner tissue to the outer layer to form a protective coating of dead skin cells. However, when referring to tumors, cell migration is dangerous. Skin tumors arise in the epidermis. The tumor then invades the dermis, creating a metastatic lesion, which breaks down tissue, including bone. This paper experiments with the two forms of morphology, elongated and rounded....   [tags: Biology]

The Excretory System

- The role of the liver is to filter toxins and remove them from the body in the form of nitrogenous waste. Nitrogenous waste is ammonia, urea and uric acid. In the human body only ammonia and urea are produced and the liver quickly changes the harmful ammonia into the tolerable urea for excretion from the body. Ammonia is toxic to humans in high concentrations (see Table 1). Ammonia is the by-product of protein being broken down. Ammonia is formed by the breakdown of amino acids taken from excess proteins....   [tags: biology, anatomy]

By this statement, I believe the authors mean that physical anthropology studies human biology with an evolutionary viewpoint rather than a scientific or medical viewpoint.

He soon realized that he does not like the study of medicine and could not bear the sight of blood or suffering. So here changed schools and went to Cambridge to become a clergyman. Then he soon noticed he would like to be a naturalist.

Biotechnology a New Beginning

- The world of biology and technology has been getting blurred more and more throughout the years. Undoubtedly you have asked someone the question why you look the way you do. There are also billions of dollars spent each and every week where people are trying to change the ways we look. Science might hold the answers to the question as to how people will be able to change their looks or much more. The key to everything is all in our genetic makeup. All of our features come down to our genetics. More than just our physical appearance these genes, our intelligence, tempers as well as all the hereditary diseases we have or will likely develop within our lifetimes....   [tags: biology, dna discovery, genetics]

Insulin Resistance and Exercise

- This is a discussion of research article listed at end of paper When muscle is damaged, there is a general resistance to insulin. The physiological stress that is associated with damaged muscle impairs how insulin stimulates IRS-1, PI 3-kinase, and Akt-kinase. This presumably leads to less glucose absorption. Previous studies have shown that there has been temporary insulin resistance due to the physiological stress associated with muscle damage. However, the molecular mechanisms by which physiological stress induces insulin resistance is not known....   [tags: Biology Muscle]

Benefits of Human Cloning

- What is cloning. "Cloning is the process of making a genetically identical organism through nonsexual means."( It has been used for thousands of years to produce plants. The next stage was to clone animals. Scientists can take unfertilized eggs of some small animals, and clone them, so they develop into full adults. After knowing that people realized how great it would be if we could clone humans. There would be a lot of advantages in cloning humans.

For centuries, this chain of volcanic islands has been used uniquely by various cultures based off distinct needs. What has remained the same however is the fact that island isolation has forced many animal and plant species to adapt differently from one another based off their island’s environmental conditions, creating a living model of microevolution over time....   [tags: biology, evolution, conservation]

Evolution: More Than One Level

- Evolution: More Than One Level The evolution of art mimics biological evolution. For this reason art history and biology are comparable in many ways. Works of art are stories. Each work of art relates to and influences other stories, or pieces of art. Ernst Mayr uses the phrase "descent with variance" throughout his book to describe biological evolution. Art behaves similarly. In addition, like biological evolution there are serious ramifications for the production of art. Because it is possible to view art from an evolutionary perspective it is also possible to look at evolution from an artistic perspective....   [tags: Science Art Biology Essays]

Large Amounts of Glutamine as the Cause of Disease

- Neurodegenerative disorders such as Alzheimer's disease and Parkinson's disease are caused by the aggregation of abnormal proteins in neurons. An essential component of cellular function is the correct assimilation of proteins in the cell. Proteins fold into specific structures and then carry out cellular functions. However, when this folding process runs amuck, abnormal proteins are introduced into the cell. In neurodegenerative diseases, these protein aggregates are characterized by having genes which contain too many CAG trinucleotides repeats that encode for polyglutamine (polyQ)....   [tags: Biology Alzheimers Parkinsons]

Are Our Morals Genetically Determined or Merely Assumed?

- In a recent commentary for BBC News, Clark McCauley, Professor of Psychology at Bryn Mawr College, analyzed the issue of human evolution from a standpoint that drew on his knowledge of psychology: gradual and collective changes in human behavior. According to McCauley, as environments and situations changed, human behavior was forced to adapt accordingly. In his comments, McCauley cites the example of disgust; although it is now a common human reaction, McCauley claims it once did not exist. As humans became less capable of digesting raw meat, disgust became an important deterring force that, through the process of evolution, became a familiar and shared part of human existence....   [tags: Philosophy Biology Essays]
