Brave New World Type Of Cloning
1,547 wordsOne of the latest advancements in technology is that of cloning. Cloning is the process of creating an identical copy of an original. In general, cloning is used in three contexts. First is using specialized DNA technology to produce multiple, exact copies of a single gene or other segment of DNA. This process is called cloning DNA. A second type of cloning exploits the natural process of cell division to make many copies of an entire cell. A third type of cloning produces complete, genetically ...

Blood Flow Hepatitis B
826 wordsCirrhosis is a serious disease of the liver where scar tissue replaces normal healthy tissue, and affects the function and structure of the liver. Liver, which is the largest organ in the body, has a vital roles which are important to keep the body functioning well. Liver makes proteins and enzymes that regulate blood clotting. It also regulates cholesterol and stores the energy. In addition, the liver removes poisons from the blood. 30 % of cirrhosis's victims are diagnosed will remain alive fo...

Cell Membrane Electron Transport Chain Biochemical Pathway
684 words1. The cell membrane structure is vital to the life of the cell. The cell membrane is shaped as having a phosphate head at the very outer surface, and two fatty acid tails hanging from it. The membrane is double, so at the tip of the fatty acid tails, there are two more fatty acid tails attached to another phosphate head. This is what it looks like: The reason the cell membrane is shaped like this is mainly to control the water flow in and out of the cell. Water is very important to the cell: if...

Hepatitis C Illegal Drugs
1,264 wordsMy uncle was not the only person to become infected with the hepatitis C virus, but in fact many people are presently struggling to keep it under control. Today four million Americans are infected with the hepatitis C virus and there are thirty thousand new cases of this virus found each year (Turkington 9). Hepatitis C takes ten thousand lives each year just in the United States, and without effective treatment the death rate is expected to triple in the next fifteen years (Turkington 9). Seven...

Gel Electrophoresis Chain Reaction
892 wordsHuntington Disease, (HD), is a hereditary degenerative brain disease. Usually begining in mid-life, cells in the caudate nucleus of the brain begin to die, causing a relentless deterioration of intellectual ability, emotional control, motor skills, balance and speech. Chorea, or involuntary movements, is nearly always a symptom as well. HD is caused by a single dominant gene. Every child of an affected parent has a 50 % chance of inheriting the gene that causes HD. The HD gene is found on chromo...

Sense Of Individuality Organ Transplants
1,080 wordsA clone is the name given for a group of organisms or other living matter with exactly the same genetic material. Genetic material consists of genes, which are the parts of cells that determine all characteristics of living things. It is not until recently that scientists have developed an experimental process for cloning higher animals, such as humans. This is a very technical process which involves first destroying the nucleus of an egg cell from the species to be cloned. Then a nucleus is rem...

Studying The Human Genome Project
801 wordsThe Human Genome Project is a 15 -year international research program to find the estimated 80, 000 human genes and determine the sequence of the three billion DNA building blocks that underlie all of human biology and its diversity. The purpose of The Human Genome Project will characterize the genomes of human and selected model organisms through complete mapping and sequencing of their DNA. It will also develop technologies for genomic analysis and examine the ethical, legal, and social implic...

Blood Cells Circulatory System
332 wordsOverview Snake venom is the poison fluid normally secreted by venomous snakes when biting. It is produced in the glands, and injected by the fangs. Snake venom is used to immobilize and / or kill prey, and used secondarily in defence. It is a clear, viscous fluid of amber or straw colour. There are two main types of venom produced by snakes, containing primarily either: Neurotoxins - these attack the nervous system. Hemotoxins - these attack the circulatory system. While most snakes' venom conta...

Role In The Nitrogen Cycle Nitrogen From The Atmosphere Tree
374 wordsThe nitrogen cycle is a complex biological cycle involving the recycling of usable nitrogen. If this cycle ceased to occur, all forms of life on the planet would die. All life forms, including humans, use nitrogen in compounds called amino acids. These amino acids then act as building blocks for proteins. Nitrogen, in fact, is the most abundant element in the atmosphere. Most organisms are unable to use this nitrogen from the atmosphere and rely on the nitrogen in the soil. The cycle consists of...

Cystic Fibrosis Enucleated Egg
2,092 wordsThe first thing that must be cleared up is what is cloning, and what is a clone. A clone is an organism derived asexually from a single individual by cutting, bulbs, tubers, fission or parthenogenesis reproduction. Parthenogenesis reproduction is the development of an organism from an unfertilized ovum, seed or a spore. Hence, cloning, biologically speaking, is any process in which production of a clone is successful. Thus, the biological term cloning is the production of genetically identical d...

Central Nervous System Spinal Cord
888 wordsSpinal Cord Regeneration Spinal cord injury can occur in many ways ranging from gunshot wounds, stab wounds and also bone displacement. These circumstances can lead to the death of neurons, and the demyelination of axons which causes some loss and damage to neurons. As Hudgins (1998) reports after a primary injury such as above, secondary injury occurs 30 minutes after and also that secondary injury is when the most critical damage occurs. This is when there is hemorrhaging in the gray matter of...
