"Hansen's Disease in Ancient DNA Samples"

Download file to see previous pages Mycobacterium leprae, the etiological agent of leprosy was identified by G. H. A. Hansen in the 19th century and therefore leprosy is also called as Hansen's Disease (Alter et al., p.19). “It is transmitted through mucous secretions of the diseased individual. The symptoms of the disease include hypopigmented lesions enlarged peripheral nerves and skin anesthesia”(Piris et al., p.125) “Hansen's disease, also known as leprosy, remains an important public health problem throughout the world. The causative microbe in Hansen's disease is Mycobacterium leprae, an acid-fast organism that is difficult to grow in vitro” (Legendre et al., p.27). Hansen's disease is one of the oldest diseases reported in the history. Holy Bible, both New Testaments and Old Testaments, say many incidents related to the leprosy patients. As in the case of AIDS or HIV, it is difficult to predict how leprosy evolved in this world. Medical scientists are currently analyzing ancient DNA samples to find out more details about the origin of Hansen's disease. Anuja et al (2011) pointed out that “tissue changes in oral tissues do happen in some cases of leprosy and the causative organism Mycobacterium leprae can be demonstrated” (Anuja et al., p. 31). ...
DNA is the molecule that contains the genetic information needed for a living organism to develop and function. When an organism dies the DNA molecules start to degrade, breaking up into shorter strands. These fragments are sections (?sequences?) of the original DNA and can be used in ancient DNA comparisons and identifications (Elderset al., p.2). “Ancient DNA studies allowed us to study organisms that went extinct more than ten thousand years ago, to reconstruct their phenotypic traits and evolution” (Grigorenko et al.). According to Mitchel et al., (2005), “Ancient DNA contains information pertinent to numerous fields of study including evolution, population genetics, ecology, climatology, medicine, archeology, and behavior” (Mitchel et al., p.265). However, it is extremely difficult to collect such DNAs because of the inability of it to survive longer periods. Taking DNA’s from archaeological human remains will help the medical science immensely in getting more details about leprosy. But, it is extremely difficult to detect DNA remnants in Human skeleton collected from countries in which hot and humid conditions exist. For example, it is difficult to collect suitable DNA samples from human skeletons found in Asian countries because of the comparatively hot climate exists in this part of the world. An integral aspect of any ancient DNA (aDNA) work is to deal with inevitably aged and degraded specimens, most commonly bones or teeth. Despite countless samples being available, only a few are suitable for aDNA studies as little or no DNA has survived over time. In the attempt to facilitate the identification of samples with adequate DNA preservation, indirect measures of preservation have been ...Download file to see next pagesRead More

...chromatids separate, producing haploid cells with unreplicated chromosomes. Ideally, 4 daughter cells are produced per meiosis of a –gonium, and this is what happens in the production of sperm cells. However, in the case of female gamete formation, 2 daughter cells (1 from meiosis I and 1 from meiosis II), only 1 oocyte is produced from a cycle of meiosis (Campbell and Reece, 2002). DNA replication occurs in preparation for cell division How does DNA replicate? A part of the double-stranded DNA (dsDNA) unwinds, allowing DNA polymerase and DNA ligase to get into what is known as the replication bubble. The DNA polymerase adds the...

...? The Unique Qualities of Blood, DNA, and Mitochondrial DNA Your The scene is so common its almost cliche: the courtroom drama climaxing with the identification of the killer by irrefutable DNA samples presented in court; yet what are these samples actually made of, and how do lab technicians utilize the unique qualities of human tissue to make specific identifications? The answer lies in deoxyribonucleic acid (DNA), and its unique composition. Like a fingerprint, each person has a unique DNA sequence that contributes to their individuality (NIH). DNA then goes on to encode for unique proteins that act as markers in the blood, which help lab technicians make specific identifications (NIH). Similarly, mitochondrial DNA can be used... these...

... DNA: The Basis of Life The question of “What is life, and what is it made of” has been asked to the point of making it cliche,if not ubiquitous, yet a multitude of answers persist. Life could be defined as a potential, as a response to external stimuli, or even as an indefinable feeling, yet none of these answers attempts to solve the question of what actually drives the biological engine of our bodies that keeps us breathing, pumping blood, and absorbing food. On April 25th, 1953, the now famous scientific pair of Watson and Crick attempted to finally answer this question (Fredholm). They claimed that an elegant molecule called deoxyribonucleic acid, or DNA, was the “God Molecule”, the blueprint for every protein in our body... (and the...

It is an incurable condition and merits importance because it is the most common cause of dementia. The characteristic feature of the disease is disruption of cognition and behavior of the individual. It is a public health problem and often diagnosed after 65 years of age (Anderson, 2010). Individuals with this problem are irritable, confused and have swings in mood. They can be aggressive and have breakdown in language. They usually have long term loss in memory and fail to acquire new memories. The condition occurs due to...

...in modern years as stem cell research has gained media attention and been the topic for scientific innovation (“Stem Cell Basics”, 2010). The study of DNA is important to a number of scientific fields, including biology and medicine. Understanding DNA allows scientists to better understand how cells work and to develop new therapies for genetic disorders. In the future, modifications to the DNA code may be sued to prevent or treat diseases. Genetic modification is already being used in some cases to produce healthier plants and animals, or mass produce antibiotics using bacterial vectors (Calladine, 2004). DNA has many applications and is...

...Centers for Disease Control (CDC) Report on Assisted Reproductive Technologies (ART) In this review, we feature a particular peculiarity observed in selecting a sample of ten ART cycles. In this selection, all cycles selected ended up being those that had resulted in no pregnancy. Just how possible is that? We take some little insights from the theory of probabilities to try and find out and explain how this could have happened. In probability theory, outcomes are bound to take any of the available alternatives. Both in theory and in practice, the probability of selecting alike outcomes over consecutive trials remain live as long as that alternative remains present. To determine whether this particular...

...FLUORIDE IN TEA SAMPLES (Introduction to an experimental procedure) of (affiliation) Name: Chemistry Date Submitted: November 17, 2014 Introduction Fluoride is an inorganic mineral that can be found naturally in many foods and liquids. It is an anion of flourine which means fluoride has a negative charge due to the presence of one extra electron (its chemical formula is F-). All tea leaves contain fluoride and older leaves have a higher level of fluoride content. Scientific research studies indicated that people who often drink tea in large amounts are susceptible to develop a painful bone disease called skeletal fluorosis. Its symptoms are joint pain similar to arthritis and bone loss similar to...

The assessment also seeks to identify the causes of the disease while at the same time discussing the areas of the brain affected. Additionally, the paper will discuss the possible treatment method for the disorder. The disease is the continuous destruction of the brain tissue, which causes the weakening and loss of mental capacity. It starts with a seemingly harmless loss of memory and other cognitive skills. This culminates in a state of complete dependence on help requiring total assistance with personal hygiene and feeding...
