Gene Pool Natural Selection
1,169 wordsvolution is the cornerstone of modern biology. It unites all the fields of biology under one theoretical umbrella. It is not a difficult concept, but very few people -- the majority of biologists included -- have a satisfactory grasp of it. One common mistake is believing that species can be arranged on an evolutionary ladder from bacteria through "lower" animals, to "higher" animals and, finally, up to man. Mistakes permeate popular science expositions of evolutionary biology. Mistakes even fil...

Phenylalanine Hydroxylase Pah Enzyme Phenylalanine Hydroxylase Pah Pku
899 wordsPhenylketonuria is one of the commonest inherited disorders - occurring in approximately 1 in 10, 000 babies born in the U. S. It occurs in babies who inherit two mutant genes for the enzyme phenylalanine hydroxylase (PAH). This enzyme normally breaks down molecules of the amino acid phenylalanine that are in excess of the body's needs for protein synthesis. Because we inherit two copies of the gene for the enzyme, both must be defective to produce the disease. A laboratory test that measures ho...

Dawkins Uses The Example Dawkins Explains Genes
1,178 wordsIn the popular science book, The Selfish Gene, Richard Dawkins explains his theory of evolution, and its occurrence for the good of the gene rather than the good of the species or individual. Dawkins believes the gene to be practically immortal, carrying on generation upon generation. By calling them selfish Dawkins describes a genes strategy of competition for survival, its tendency to behave in a manor suited to ensure its propagation. Genes are competing directly with their alleles for surviv...

Human Genome Project Cystic Fibrosis
1,610 wordsFetal DNA modification, what is it? Fetal DNA Modification is a type of germ line gene therapy, but it is only performed on fetuses. This is because of their abnormalities of their gene makeup that could cause hereditary disease. If a genetic disease is found during the test of the amniotic fluid, then Fetal DNA therapy could be an excellent choice. Since the human genome project is nearly completed there is now the knowledge of where each gene in the human body is located and what its use is. W...

Recombinant Dna Selective Breeding
1,183 wordsIf you have had a can of soft drink, ate a fruit, or took some head ache medicine this morning - then it's very likely you have used a genetically enhanced product. Genetics is a part of biotechnology that manipulates biological organisms to make products that benefit humankind. Biotechnology is essential in our life, but there are some concerns regarding its safety. Although, biotechnology may pose some danger it is proving to be very beneficial to humankind. The first applications of biotechno...

Duchenne Muscular Dystrophy Muscular Dystrophy Association
745 wordsMuscular Dystrophy Scientists have been struggling with the cause, treatment of, and cure for Muscular dystrophy since its discovery in 1886, by Dr. Guillaume Duchenne. Muscular dystrophy is a hereditary disease, affecting thousands of people every year, two-thirds being children between the age of birth through adolescents. However, Muscular dystrophy can occur with no family history of the disease. Muscular dystrophy is a degenerating disease, in which the skeletal muscles degenerate, lose the...

Transgenic Animals Human Cloning
1,487 words... ls with an apparently desirable genetic constitution. If Dolly represents one genetic copy of her mother then nuclei from the thousands of other udder cells could, with a sufficient supply of host eggs, produce a thousand Dollies - a thousand genetic replicas - in a single generation. However, here theory and practice diverge. Dolly was a single sheep produced from nearly three hundred attempts, without even counting the previous years of failed experiments. With a single result of this kind...

Somatic Cell Therapy Germ Line Therapy
1,485 wordsScience is a creature that continues to evolve at a much higher rate than the beings that gave it birth. The transformation time from tree-shrew, to ape, to human far exceeds the time from analytical engine, to calculator, to computer. But science, in the past, has always remained distant. It has allowed for advances in production, transportation, and even entertainment, but never in history will science be able to so deeply affect our lives as genetic engineering will undoubtedly do.

Color Blindness Defective Gene
981 wordsColor Blindness Genetic disorders result from heritable abnormalities in the genetic makeup of a human. Disorders are often apparent at birth; however, others may develop during childhood or adult life. Some genetic disorders may result from a mutation in a single gene, which results in the absence or alteration of the protein that corresponds. Such an alteration disrupts some metabolic or developmental process, leading to a disease. Color blindness is an example of a disorder that can be inheri...

Obsessive Compulsive Disorder Deficit Hyperactivity Disorder Adhd
4,751 wordsDifferential Diagnosis Today the full-blown case of TS is unlikely to be confused with any other disorder. However, only a decade ago TS was frequently misdiagnosed as schizophrenia, obsessive-compulsive disorder, Sydenhams chorea, epilepsy, or nervous habits. The differentiation of TS from other tic syndromes may be no more than semantic, especially since recent genetic evidence links TS with multiple tics. Transient tics of childhood are best defined in retrospect. At times it may be difficult...

Sexual Orientation Le Vay
1,387 wordsIs it Gay Gene Homosexuality Is it Really a Choice? Since the 1800 s, psychiatrists and psychologists have concluded that homosexuality is a mental disorder. They have believed it is brought about by misguided upbringing and their social environments. For instance, it was believed that if the child was lacking a male figure in the home, he would most likely be gay. Or that child abuse can lead to lesbianism when the special needs of a little girl are denied, ignored, or exploited and the future ...

Ovarian Cancer Oral Contraceptives
4,183 wordsOf all gynecologic malignancies, ovarian cancer continues to have the highest mortality and is the most difficult to diagnose. In the United States female population, ovarian cancer ranks fifth in absolute mortality among cancer related deaths (13, 000 /yr). In most reported cases, ovarian cancer, when first diagnosed is in stages III or IV in about 60 to 70 % of patients which further complicates treatment of the disease (Barber, 3). Early detection in ovarian cancer is hampered by the lack of ...
