Extract of sample "Mendel's contribution to medicine"

What Has Been Mendel's Contribution To Medicine Mendel was an Austrian monk and botanist who discovered how characteristics are inherited. He patiently carried out thousands of experiments on pea plants and studied

the results of cross-fertilization among them. He discovered that inheritance does not

work by blending maternal and paternal characteristics together, instead they are

inherited in pairs. In each pair, only one characteristic is only expressed. Mendel worked

out the basic principles of present-day genetics, but scientist could understand the

significance of his work and rediscover him only in twentieth century.

Three of Mendel's postulates are, law of unit factor, law of dominance and

recessiveness, and law of segregation. Inherited characters are determined by a pair of

contrasting factors or determinants, and this led to establishment of law of unit factors.

Presently, these determinants that occur in pairs are called allele, and each pair together is

called an allelic pair. They occupy a specific portion of the chromosome in a cell, and

that is known as gene. Thus, gene is the inheritance unit that is responsible for a specific

character in the offspring.

When two alleles are brought together for expression of a trait, only one expresses

itself, and the other remains suppressed. That which is expressed is called dominant, and

the other recessive. This is called law of dominance and recessiveness.

The word "segregate" means to separate. According to the law of segregation,

during the formation of gametes, the two alleles separate from each other so that each

gamete gets any one of them. It was also shown by Mendel that males and females

contribute to the inherited traits in the offspring equally, and the traits that are acquired

are never inherited.

After Mendel's theories and laws were way past forgotten, new interests in this

field of science raised questions about the factors or determinants mentioned by him. The

search for answer to these questions led to the discovery of chromosomes and genes. It

also helped Sutton and Boveri to establish the chromosome theory of inheritance.

Combining this theory and Mendel's law of dominance and recessiveness made the

detection of human genetic disorders easy. It was shown that most of the genetic

disorders, such as, Tay-Sachs disease, sickle cell anemia, etc., are determined by

recessive alleles. However, few of the genetically transmitted diseases are also

determined by dominant alleles. Huntington's disease is an example of this.

Mendel's suggestion that there is an unit factor responsible for a specific character,

led to investigations, and this in turn, led to the discovery of DNA or deoxyribonucleic

acid in a chromosome. This DNA started to be considered as unit of life, and almost all

cellular events were able to be explained with the concept of DNA. This and related

research developed the science of Genetics and led the foundation stone of another

science, Biotechnology. Biotechnology, in turn, boosted its growth by development of

recombinant DNA and hybridization technologies.

Biotechnology often seems to be affecting the present age Medicine. By

recombinant DNA technology, which is a derivative of Mendelian concept, the whole

outlook of molecular basis of life and interventions into it has changed. Recombinant

DNA technology has helped in the artificial synthesis of genes, isolation of desired genes

or DNA segments, modification of gene, repairing of defective DNA segments to change

defective phenotype. We can directly correlate this to Mendel's discovery. According to

Mendel, phenotype or outward appearance of a trait is derived from genotype or genetic

make up of the organism. Recombinant DNA technology has been used for the

production of many medicines, such as, somatostatin, insulin, vitamins, antibodies, or

vaccines to which the present-day medical therapeutics is indebted.

DNA technology can be used in diagnosis of a disease too. It has enabled detection

of carriers of hereditary diseases like, muscular dystrophy, Down's syndrome, Turner

syndrome, etc.

Gene therapy is an important application of genetic engineering. With this, the

otherwise incurable hereditary diseases can be treated by replacing the abnormal genes

causing a particular disease in the stem cells of bone marrow. Severe combined

immunodeficiency disease has been treated by gene therapy.

One more major contribution of Mendelian science is creation of transgenic

animals. They are of great use to modern Medicine. Hemophilia is a disease where blood

clotting fails. The treatment consists of treating the patients with antihaemophilic factor,

but this would need a lot of donors to donate blood. This problem has been solved by

Mendelian concept that the antihaemophilic factor is synthesized as a result of particular

gene expression. The scientists have created transgenic female sheep with

antihaemophilic factor IX gene, and human antihaemophilic factor can be extracted from

the blood of these sheep.

Thus we can see how a simple observation by Gregor Mendel and the statistical

analysis of those data, even if long ignored by the scientific world, have now created the

basis for two other very big and significant sciences, genetics and biotechnology, and

in that way has boosted the modern medicine. To be honest, the modern medicine is

modern medicine for Mendel's experiments. Read More

Homeopathic Medicine - Alternative Medicine

...?Homeopathic Medicine – Alternative Medicine Homeopathy had its origins in the later part of the 18th century and developed mainly in the 1800's. Around those times only scientific advances were seen in various fields including the fields that are related to medicine like chemistry. Even with this advancement, the medical practices were imbued with irrational treatments with small ‘dosage’ of superstitions thrown in. These unfavorable situations prevailing then only spurred Samuel Hahnemann, regarded as the “Father of Homeopathy”, to come up with an alternative treatment. Although he himself was a physician with a degree in Medicine, the faults of the allopathic system only ‘circulated’ in Hahnemann’s mind. So, he started to write many...

Acupuncture and Herbal Medicine in Women's Health: Infertility in Women

Modern medicine uses techniques of in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), and assisted reproductive technologies (ART) to manage infertility in women. Herbal medicine and acupuncture attempt to normalize the reproductive system as a means to manage infertility in women.

Literature Review: Women are drawn to herbal medicine and acupuncture in the belief that it is natural, and often do not inform their physician of its use. The influence of herbal medicine in reproduction is believed through its ability to increase the thickness of the endometrial lining. The beneficial effects of acupuncture are believed to be derived from mediation through endogenous opioid peptides in the central nervou...

How Did Radio in the 1960's Mark the Changing Social Order in the UK and US

...How did radio in the 1960s mark - and even actively promote - the changing social order in the UK and US? The 1960s saw perhaps the greatest social changes in history. For the first time young people and their parents were divided. They had different cultural ideas and little middle ground to understand each other. The music tastes, social conventions and political beliefs of the older generation had been violently rejected by a disaffected youth which sought to establish a new social order. These were times of change, times of disaffection and times in which a whole new social network was being established. This took the form of underground movements, independent press and pirate radio. This essay will focus on this final tool... did radio...

Approach to Education: Comparison of Philosophies of A S Neill & Paul Hirst

He believed that to impose anything by authority is wrong. The child should not do anything until he comes to an opinion – his own opinion- that it should be done. He states clearly his commitment to freedom of a child: ‘we set out to make a school in which we should allow children to be themselves. In order to do this, we had to renounce all discipline, all directions, all suggestions, all moral training, and all religious instruction. The child should never be forced to learn, Attendance at lessons should be voluntary whatever the age of the child. Only learning that is voluntarily undertaken has any value, and children will know themselves when they are ready to learn. (Summerhill , p.37)

The 1846 Invasion into Mexico by the U. S.: The Political and Economic Forces that Brought about the Invasion

Some of the territories led to a war with Mexico from which the United States emerged victorious, expanding its territories and decisively establishing its dominance in North America.

President Andrew Jackson led an example of an administration that set the stage for the way in which James Polk would lead. In 1817, as a still yet military leader, Jackson led the United States into the first of three conflicts with the Seminole Indians from which the acquisition of Florida from Spain would be negotiated and finalized. The situation with Spain was tenuous and should have been dealt with in a diplomatic and cautious manner, but in 1817 President Monroe wrote a letter to General Jackson stating that “Great interests...

Critical Appraisal of the Research about Traditional Chinese Medicine and Acupuncture by Melchart

Fundamentally, the treatment is acupuncture but the research methodology/research design allows us to assess validate whether acupuncture really works by introducing a third situation: minimal acupuncture instead of only no acupuncture.

On closer analysis, however, what Melchart et al. (2005) described as “minimal acupuncture” is actually zero acupuncture because the “minimal acupuncture” consisted of superficial needling at non-acupuncture points and were meant to investigate whether acupuncture have placebo effects and, if so, how of its possible effects in headache is classifiable as placebo. According to Merchant et al. (2005, p. 376), acupuncture and minimal acupuncture were administered by...

...Critical Thinking about the Viet Nam Conflict; The contribution of the media Introduction The Vietnam War is one of the major conflicts that have taken place in the world. The Vietnam War took place between the year 1955 and 1975; taking a period of more than twenty five years. Although the real war began in 1955, the signs of the war could be seen as early as 1950. This was the time when US troops were sent to Vietnam. These minor conflicts in Vietnam later led to a serious war in 1955 that lasted for about 25 years. This war has caused many problems in the United States. During the war, many United States’ soldiers were sent to travel for long distances away to fight for reasons that were neither clear nor justifiable. In this war, both...
