Recent developments in the field of genetics have led to significant change in the way genetics contribute in medicine. Genomics is the human genetic information lying inside the nucleus of a human cell, which provides all the qualities, physical and psychological characteristics of a living organism. Classical genetic is a term which means the methods and techniques used in the study of genetics before the advent of molecular biology these techniques are: genetic and SNP (Single-nucleotide polymorphism) mapping, gene linkage, and pedigree analysis to identify genes responsible for traits that cause diseases (Paritosh, K. et al., 2013). Among the most important discoveries of classical genetics so-called genetic association in Eukaryotes that lead to a phenomenal research in the field of genetics (The Genome Project). The Austrian monk Gregor Mendel is the founder of classical genetics and published in 1865 (Gliboff, 2014). Nevertheless, classical genetics are no longer pertinent in the detection of genetic disorder diseases such as Asthma and several other pathologies (Sawhney, V. etl, 2014). The difference between genetics and genomics is that genomics deals with the whole genome instead of a particular gene of interest and classical genetics is a significant part in genomics that can be very useful when detecting hereditary diseases. Furthermore, medicine depends on the approach of how traits are passed from generation to another, but the mechanism of these genes and how they work is the significant part in modern medical science which cannot be identified using classical genetics. Although, Mendelian genetics do have a significant contribution in medicine, this essay will demonstrate that the usage of classical genetics is rel...

...e genes which in turn will make the process of dealing with genetic disorders more approachable. Classic genetics are solely based on the phenotype of the reproductive system, whereas; molecular biology provides a significant forward-step in medicine to search for a cure for sickle cell diseases and genetic disorders. An early diagnosis of a specific disease that occur due to a single gene disorder could significantly assist the healing process as molecular genetics researches in this field is growing rapidly, for example: CFTR-mutation screening to control the risk of cystic fibrosis. This shows that Mendelian is not relevant to medicine in modern dealing of genetic disorders. However, it is still applicable in several hospitals, especially when dealing with family genetic disorder and to identify the possibility for each individual of getting the specific disease.

Pros and Cons of Genetic Engineering Essay

- Genetic Engineering is highly controversial since some people believe that genetic engineering is playing God. As this fact there is opposition to the progression of the field by people who do not see the value in genetic engineering, or they fear what genetic engineering may lead to for us as people. There is a history of discover that belongs to genetic engineering, which has led to numerous products that have emerged which have brought numerous applications to the society of the world. Though there are benefits to genetic engineering, there are also drawbacks to genetic engineering including ethical and legal issues that are dealt with in today’s society in order to try and regulate the...   [tags: Genetic Engineering]

Genetic Engineering: A Major Advancement for Mankind Essay

- As the Biochemist Isaac Asimov once said, "The advancement of Genetic Engineering makes it quite conceivable that we will design our own evolutionary progress.” Scientists have always thought about new ways to progress through technology in our era, and in 1946, scientists discover that Genetic material from different viruses can be combined to form a new type of virus. This was a major discovery that trickles down to the modern era of Genetics. Current scientists have pioneered new ways to decode human DNA, beating the $3 billion government-run Genome project to its goal....   [tags: Genetic Engineering]

Genetic Engineering Is Not Safe Essay

- Genetic engineering is the intended modification to an organism’s genetic makeup. There have been no continuing studies on this topic or action so there is no telling whether or not it is harmless. Genetic engineering is not safe because scientists have no absolute knowledge about living systems. Given that, they are unable to do DNA surgery without creating mutations. Any interference on an organism’s genetic makeup can cause permanent damage, hereditary defects, lack of nutritious food, or a spread of dangerous diseases....   [tags: Genetic Engineering Essays]

Genetic Engineering Essay

- Genes are, basically, the blueprints of our body which are passed down from generation to generation. Through the exploration of these inherited materials, scientists have ventured into the recent, and rather controversial, field of genetic engineering. It is described as the "artificial modification of the genetic code of a living organism", and involves the "manipulation and alteration of inborn characteristics" by humans (Lanza). Like many other issues, genetic engineering has sparked a heated debate....   [tags: Genetic Engineering ]

Essay on The Benefits of Genetic Engineering

- The engineering of deoxyribonucleic acid (DNA) is entirely new, yet genetics, as a field of science, has fascinated mankind for over 2,000 years. Man has always tried to bend nature around his will through selective breeding and other forms of practical genetics. Today, scientists have a greater understanding of genetics and its role in living organisms. Unfortunately, some people are trying to stop further studies in genetics, but the research being conducted today will serve to better mankind tomorrow....   [tags: Genetic Engineering Essays]

- Genetic engineering gives the power to change many aspects of nature and could result in a lot of life-saving and preventative treatments. Today, scientists have a greater understanding of genetics and its role in living organisms. However, if this power is misused, the damage could be very great. Therefore, although genetic engineering is a field that should be explored, it needs to be strictly regulated and tested before being put into widespread use.

Genetic Engineering: Playing God Essay

- Current technology has made what once seemed impossible, mapping the human genome, a reality within the next decade. What began over forty years ago with the discovery of the basic structure of DNA has evolved into the Human Genome Project. This is a fifteen-year, three billion dollar effort to sequence the entire human genetic code. The Project, under the direction of the U.S. National Institute of Health and the department of Energy is ahead of schedule in mapping what makes up an individual's genetic imprint....   [tags: Genetic Engineering Essays]
