    HOW ABOUT VIRUSES Just like bacteria viruses are one of the microbes that are winning the match against the humans. Viruses were the toughest one to tackle for the scientist. The shape, contents and their protective shields were the most challenging part of the fight. There are many ways one can treat cancer, but for AIDS doctors prescribe a cocktail of drugs in which some are enzyme inhibitors, protein inhibitors and while some are RNA inhibitors. This is not it in the cocktail there is more to...

    Virus is a infectious agent found in all life forms, humans, animals, plants, fungi, and bacteria. Viruses consist of genetic material, either deoxyribonucleic acid or ribonucleic acid or as most people know them as DNA and RNA. They are surrounded by a protective coating of protein, called a capsid, with or without an outer lipid envelope. Viruses are between 20 and 100 times smaller than bacteria. Viruses are not considered free-living, since they cannot reproduce outside of a living cell; th...

    Computer Viruses A virus is a program that copies itself without the knowledge of the computer user. Typically, a virus spreads from one computer to another by adding itself to an existing piece of executable code so that it is executed when its host code is run. If a virus if found, you shouldn't panic or be in a hurry, and you should work systematically. Don't rush! A Virus may be classified by it's method of concealment (hiding). Some are called stealth viruses because of the way that they hi...

    General Virus Information A virus is a piece of software designed and written to adversely affect your computer by altering the way it works without your knowledge or permission. In more technical terms, a virus is a segment of program code that implants itself to one of your executable files and spreads systematically from one file to another. Computer viruses do not spontaneously generate: They must be written and have a specific purpose. Usually a virus has two distinct functions: + Spreads i...

They infect nearly every form of life from the simplest unicellular organism (bacteria) to complex mammals, such as humans. The structures of all human viruses have several common attributes. First is their incredibly small scale. There are 10 x 10+9 nanometers in a meter. Viruses are so minuscule that they can only be visualized using ele...

Some people tend to use the word "virus" to refer to anything undesirable that can happen to a computer, but this is not completely accurate. Viruses are short programs that are not accidental. Someone, somewhere, has purposely designed them, usually with malicious intent. It is usually copied and passed along many times before it reveals its existence. "A virus is any program that reproduces itself by using the reso...

    Viruses: Complex Molecules or Simple Life Forms? Viruses have been defined as 'entities whose genomes are elements of nucleic acid that replicate inside living cells using the cellular synthetic machinery, and cause the synthesis of specialised elements that can transfer the genome to other cells.' They are stationary and are unable to grow. Because of all these factors, it is debatable whether viruses are the most complex of molecules or the simplest life forms. While the definition of living o...

    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...
