Cd 4 Cells Reverse Transcriptase
1,846 wordsThe content of this paper is whether or not mutations undergone by the Human Immunodeficiency Virus and allow it to survive in the immune system. The cost of treating all persons with AIDS in 1993 in the United States was $ 7. 8 billion, and it is estimated that 20, 000 new cases of AIDS are reported every 3 months to the CDC. The question dealing with how HIV survives in the immune system is important, not only in the search for a cure for the virus and its inescapable syndrome, AIDS (Acquired ...

Nitrogenous Bases Amino Acids
999 wordsDeoxyribonucleic acid and ribonucleic acid are two chemical substances involved in transmitting genetic information from parent to offspring. It was known early into the 20 th century that chromosomes, the genetic material of cells, contained DNA. In 1944, Oswald T. Avery, Colin M. MacLeod, and Maclyn McCarty concluded that DNA was the basic genetic component of chromosomes. Later, RNA would be proven to regulate protein synthesis. DNA is the genetic material found in most viruses and in all cel...

Amino Acids Dna Molecule
1,152 wordsIntroduction Deoxyribonucleic acid is contained in all cells. The structure of DNA makes gene transmission possible. Since genes are segments of DNA, DNA must be able to make exact copies of itself to enable the next generation of cells to receive the same genes. The DNA molecule looks like a twisted ladder. Each "side" is a chain of alternating phosphate and deoxyribose sugar molecules. The "steps" are formed by bonded pairs of purine-pyrimidine bases. DNA contains four such bases the purines a...

3,530 wordsINTRODUCTION There is no doubt that AIDS is indeed the epidemic of the decade. Not only are there many supporting facts and data, visiting urban cities and third world countries prove this point. Furthermore, AIDS is not only highly infectious, it is also the first major incurable epidemic throughout this biomedical revolution that mankind is going through. This epidemic might actually be the one that will completely wipeout the third world. Scientists, government agencies and pharmaceutical com...

1,948 wordsDNA: The Making Lyle Sykes For more than 50 years after the science of genetics was established and the patterns of inheritance through genes were clarified, the largest questions remained unanswered: How are the chromosomes and their genes copied so exactly from cell to cell, and how do they direct the structure and behavior of living things? This paper will discuss those questions and the people that answered them. Two American geneticists, George Wells Beadle and Edward Lawrie Tatum, provided...

Ebola Hemorrhagic Fever Ebola Reston
2,699 wordsThe Ebola Virus is the common name for several strains of virus, three of which are known to cause hemorrhagic fever in humans, which is characterized by massive bleeding and destruction of internal tissues. Named for the Ebola River in Zaire, Africa, where the virus was first identified, the Ebola virus belongs to the family Filoviridae. Three strains of Ebola virus that are often fatal to humans have been identified. Named for the areas in which the first recognized outbreaks took place, these...

Endoplasmic Reticulum Hemorrhagic Fever
3,146 wordsHantavirus: A Four Corners Study When a new virus appeared in the Four Corners region, American scientists were stumped. What was causing such a quick death to such healthy people? Was there a potential epidemic on their hands? No one knew, and when they finally determined that a strain hantavirus was involved, many were shocked. This had to be something completely new to the hantavirus family and that was somewhat overwhelming. Normally, the hantavirus only affects the kidneys, but this new vir...

Human Genome Project Dna Sequences
5,742 wordsLife as we know it is specified by genomes. Every organism possess a genome that contains the biological information needed to construct and maintain a living example of that organism. Most genomes, including those for all cellular lifeforms, are made of DNA (deoxyribonucleic acid) but a few viruses have RNA (ribonucleic acid) genomes. DNA and RNA are polymeric molecules made up of linear, unbranched chains of monomeric substances called nucleotides. Each nucleotide has three parts: a sugar, a p...

Sickle Cell Anemia Red Blood Cells
1,326 wordsThe Protein Site Protein Synthesis The process of Protein Synthesis involves many parts of the cell. Unlike other similar productions, this process is very complex and precise and therefore must be done in proper sequence to work effectively. The slightest error during this process could cause the action to experience difficulty or even fail. For example, in the production of starch, glucose molecules are combined to be stored and eventually utilized as usable chemical energy. The cell can break...

Signs And Symptoms Infectious Diseases
1,203 wordsIntroduction to viruses: For centuries submicroscopic organisms, also known as viruses, that grow and multiply at different rates inside of a cell, have been circulating our planet. 1 The cell produces the various, essential components of the virus. These components are: 1) DNA or RNA nucleic acids, which are the genes of the virus. Viral particles posses either DNA strands or RNA strands, but never both in contrast bacterial infections contain both. The amount of DNA/RNA in a virus changes depe...

Made Of Proteins Binds To The Small Rna
647 wordsProteins are some of the most essential compounds on the planet. They perform a variety of tasks ranging from muscle contraction to fighting diseases. Over 50 % of the dry weight of organisms are made of proteins; this is because things like your nails and hair are made of proteins. Proteins are also components of biological membranes, and they help regulate the passage of molecules through the membranes. This is all very important to the body, but the most important function, by far, is their u...

Darwin Theory Earth Surface
2,710 wordsEvolution, a process of change through time, is what links together the enormous diversity of the living world. A lot of evidence is present that indicates that the earth has had a very long history and that all living things arose in the course of that history from earlier, more simpler forms. In other words, all species have descended from other species and all living things share common ancestors in the past. Basically, organisms are what they are because of their history. Today there are man...
