AIDS By Adam Hans A virus is the smallest particle that consists of a nucleic acid and it attacks your cells just like the Aids virus. They can not replicate themselves it must use a host cell. For instance, if we were to catch a cold our cells would be the host cells. They attach to the h...

In the 1940's the attention of geneticists was surprisingly focused on the Escherichia coli, colon bacterium. E. coli offered many advantages such as genetically being simpler, they are easily broken open and bacterial cells have little internal structure. For the fact that the E. coli popul...

Virus Essay A virus is a strand of hereditary material coated by protein. They are too small to be seen by a light microscope and can take many shapes and forms. They can also do many different things. Viruses have neither a cell membrane nor nucleus or any other organelles. Viruses are ...

ATM stands for Asynchronous Transfer Mode. It is a high speed mode of transporting data from one point to another. With ATM, you are able to transmit voice, data and video in small data packets over a single network. It can carry traffic at speeds up to 622 Mbps. Data is transmitted in fixed lengt...

Genetics. A science that has through the ages been the center of not only scientific debate but religious and morale ethic discussion. Recent genetics has caused uproar in such discussions especially in the science of the ever growing genetic cloning. Since the successful cloning of many animals ...

Viruses and Bacteria are Both Pathogenic to Humans This statement is almost true. All viruses are pathogenic but not necessarily to humans, and not all bacteria are pathogenic. All viruses are pathogenic. They may not all be pathogenic to humans, they may infect plants or other organisms. They...

The mitochondrion is an organelle found in eukaryotic cells (Tortora 1992). A mitochondrion can occur in different shapes inside one cell. Mitochondrion can be long, like a rod, and filamentous or compact, like a sphere, and granulelike (Wolfe 1993). There are approximately 1700 mitochondria in...

Parasitic animals, such as tapeworms, can live inside of another organism with no harm. Organisms that live in guts has a specific surrounding that can pass through the acid of stomach with no harm. Organism, like the tapeworm, can regenerat, if the segment of the organism is ingested by another p...

Tay-Sachs Tay-Sachs disease is a genetic disorder that occurs in children. This disease causes their central nervous system to breakdown, which in turn is the basis for their death. The disease is named for Warren Tay and Bernard Sachs. Tay-Sachs disease is caused by the absence of an enzyme...

Blood transfusion A blood transfusion is the removing of blood or blood blood-based products from the blood stream an inserting it into another circulatory system to replenish lost or damaged blood. blood transfusions can be extremely dangerous when not held in the correct environment with trained ...

Cloning A clone is a cell, group of cells, or organism that is descended from and genetically identical to a single ancestor. Or to look at in another view, a clone is a copy, an organism descended asexually form a single ancestor. There are different types of cloning however, and cloning tec...

There are several theories on aging in humans due to genetics. There are four main theories involving genetics and these are the wear and tear theory, the free radical theory, cross-linking theory and somatic mutation theory. Aging is defined as "The process of growing old or maturing." Mo...
