  • Genes From Other Living Organisms
    3,577 words
    Over the past several years Genetics has become a leading link to understanding how our body works. By mapping out deoxyribonucleic acid, or DNA, scientists plan to find cures for various diseases, develop better, more efficient drugs, grow new organs, evaluate environment hazards, and eventually build a human being. Inside of every single cell in our bodies there are 46 chromosomes that are made up of DNA. Half of your chromosomes are inherited from each parent, DNA is strung along the chromoso...
  • Functional Gene To Cells
    1,457 words
    quantities of material with which to work. The process of engineering a DNA fragment into a vector is called "cloning", because multiple copies of an identical molecule are produced. Another way, recently discovered, of produ sufficient c ing many identical copies of a particular DNA fragment is polymerase chain reaction. This method is rapid and avoids the need for cloning DNA into a vector. Therapy. form of genetic engineering involves supplying a functional gene to cells lacking that function...
  • Identification Of The Abnormal Gene
    353 words
    Cystic Fibrosis Cystic Fibrosis, is a genetic disorder of the exocrine glands, affecting children and young people; median survival is 25 years in females and 30 years in males. It is caused by a genetic abnormality in the CF trans membrane conductance regulator (CFTR) gene that results in the disruption of chloride transfer across cell membranes. As a consequence, chloride ions build up in the cells of the lungs and other organs. Water stays inside the cells to dilute the chloride rather than b...
  • Research Into The Cause Of Cystic Fibrosis
    433 words
    For a child with cystic fibrosis life is mostly a series of infections doctors visits and medications. Cystic fibrosis causes a build up of mucus in th lungs making breathing difficult. The thick mucus coats the hairlike projections lining air passage weakening the body's immune system. Excess mucus interfere with the functioning of other too. In the liver and pancreas mucus blocks the flow of the digestive enzymes in the intestine so food is not digested properly. Worn down by the repeated bout...
  • Genetic Engineering And Gene Therapy Research
    1,164 words
    Cancer is diagnosed in almost 1.5 million people in the United States annually. Approximately one-half million Americans die of cancer annually, making it the second leading cause of death in the U.S. Cystic fibrosis is an inherited, fatal disease occurring once in every 2,500 Caucasian births and once in every 17,000 African American births. Genetic research has failed, so far, to solve many genetic-based cancers, but it has identified the gene and its location (on chromosome 7) responsible for...
  • Lac Operon In Bacterial Cells
    276 words
    Describe the operon hypothesis and how it explains the control of the messenger RNA production and the regulation of protein synthesis in bacterial cells. The operon is a group of genes coding for proteins with related functions and they are arranged in units. The operon is made up of the promoter, structural genes and the operator. Transcription depends on the regulator, it may be located anywhere on the bacterial chromosome. The regulator codes for the repressor, which binds to the operator. W...
  • Study Animal The Same Gene
    339 words
    Transgenic Organism, plant, animal, or bacteria that has been genetically modified to contain a gene from a different species. The new gene is inherited by offspring in the same way as the organism's own genes. The transgenic condition is achieved by injecting the foreign gene into the fertilized egg or into embryonic cells. The injected gene becomes part of the host cell's deoxyribonucleic acid (DNA) within the chromosome and is then inherited by all the cells produced during embryonic developm...

A Brief History of Sickle Cell Disease Sickle Cell Disease in African Tradition Sickle cell disease has been known to the peoples of Africa for hundreds, and perhaps thousands, of years. In West Africa various ethnic groups gave the condition different names: Ga tribe: Chwechweechwe Faut e tribe: Nwiiwii Ewe tribe: Nuidudui Twi tribe: Ahotutuo Sickle Cell Disease in the Western Literature Description of Sickle Cell Disease In the western...
  • Human Genes In Hopes
    1,473 words
    Genetic scientists have been busy creating all kinds of solutions to some of the problems that the human and agricultural populations have been experiencing. One of the most promising has been in the area of transplantation. That is how Dolly the sheep, came about. Scientists have been trying to find a way to genetically engineer animals so that they can produce organs for humans that will not be rejected. Insulin from pigs has helped diabetics, pig valves can be used in cardiac repair, and pig ...
  • Stem Cells
    321 words
    This is about an amazing potential in medicine and health, the ability to eliminate any problem anywhere in your body by repairing it with perfectly good cells that are made by differentiating stem cells. Lets first start out by explaining exactly what stem cells are, where they came from, and why they are so important. Stem cells are blank cells to be? Andrew Jackson, our 7th President of the United States, manages to capture the imagination of masses. He attracted the admiration of some and th...

  • Dominant Q 6 What 2 Gene Combinations
    716 words
    Short notes: 1.) Cystic Fibrosis: Abbreviated as CF and also called mucoviscidosis. It is a common hereditary disease in which cells of certain glands in the body secrete large amounts of abnormally thick mucus. Accumulation of thick mucus can block products of these glands and eventually block passage of seaways of organs into which the ducts empty. Symptoms are constant cough, which expels thick mucus, etc. Lung problems are most common cause of death for cystic fibrosis patients. CF can be di...
  • Deactivated Genes From The Pregnant Mouse
    614 words
    Caleb Pan Report # 1 Problem The problem of the experiment is how a diet in a pregnant mother can change genes in her offspring. Scientists used a fat yellow mouse that carried a gene made the color of their coat different and leads to obesity, diabetes, and cancer in the mouse. If scientists can figure out this strange occurrence, they are able to help human beings in perfecting their diets and may even lead to better drugs to minimize the risk of cancer and obesity. Observations During methyla...
  • Its Genetic Material Into The Tumour Cells
    1,260 words
    Over the past decade genetic engineering has moved from the realms of fantasy to reality thanks to the sequencing of the human genome and developments in molecular biology techniques. A definition of genetic engineering is "the manipulation of DNA using restriction enzymes which can split the DNA molecule and then rejoin it to form a hybrid molecule". It is the introduction of genes into existing cells; this may be used to prevent or cure a wide range of diseases or perhaps to genetically alter ...
  • Nompc Like Gene In Vertebrate Hair Cells
    657 words
    Sensation is converting physical stimuli into electrical currents, known as action potential (AP), via transduction; hence, scientists study extensively to find out the mechanism of transduction. However, no all is clear. In this paper, Dr. Walker and his colleagues studied mechanoreceptor mutated flies, with nompC gene (described in details in his paper) of NOMPC channel, and compared their channel domain of NOMPC with other organism. Drosophila, the fly that Walker used to study, has very inte...
  • Gene Therapies For Diseases
    287 words
    GENE THERAPY Gene therapy is used to treat diseases. It comes from advances in genetics, molecular biology, clinical medicine and human genomics. Gene therapy is when you add a gene into a cell. Then the virus has to be modified to have a non-harmful virus-derived vector. This vector is a type of vehicle that can be used to carry a gene to cure the disease. Gene therapy requires the use of tools. The tools need to have a capacity to cross the cell membrane and sometimes even the cell nucleus to ...
  • Th 1 And Th 2 Cells
    570 words
    T cells are a subset of lymphocytes that play a large role in the primary immune response. These cells exhibit phenotypic and / or functional heterogeneity [1]. Phenotypic heterogeneity arises from the expression of different markers on the cell surface. There are two well-defined subpopulations of T cells, namely T helper (Th) and T cytotoxic (Tc) cells, both of which express one or the other of two membrane glycoprotein molecules CD 4 and CD 8. T cells that express CD 4 i.e. Th can only recogn...
  • Cells With Damaged Genes
    1,213 words
    When we gain control of the gene responsible for the phenomenon of apoptosis, we will be in control of aging. We are finding more evidence every day, indicating genetic links to all sorts of factors in the human being. We are just now beginning to scratch the surface of our own genetics. A landmark discover has just been unveiled: In February [2001], the two groups charting the human genome published their results– the entire 3 billion base pair sequence. The only definitive conclusion so ...
  • Vivo And Ex Vivo Gene Therapy
