Important To Understand University Of Texas
1,893 wordsAn Introduction To Telomere and Telomerase The telomere-telomerase hypothesis of aging and cancer is based on the findings that most human tumors have telomerase activity while normal human somatic cells do not. An emerging hypothesis is that the up regulation or re expression of telomerase is a critical event responsible for continuous tumor cell growth. In contrast to normal cells, tumor cells show no loss of average telomere length with cell division. Through this suggestion immortal ization ...

Human Genome Project Dna Fragments
1,943 wordsGene Mapping began when the U. S. Government held a conference to explore if DNA damage occurred in people exposed to low levels of radiation in Japan after the 1945 Atomic Bombs. There, scientists quickly realized that observing the human genome could be useful in discovering environmental mutates. Shortly afterwards, Renato Dulbecco revealed the entire sequence of human DNA and had a great impact on cancer research (Purves, et al. 1998). In 1990, scientists from around the world began the Huma...

Human Genome Project Dna Fingerprinting
990 wordsHuman Genome Project The Human Genome Project (HGP) is an international 13 year effort that began in October of 1990. The main objective of the project is to map the entire human DNA sequence. The project was planned to last 15 years, but rapid technological advances have moved the completion date to 2003. A rough draft of the human genome was completed in June 2000. Efforts are still underway to complete the finished high quality sequence. Many laboratories around the United States receive fund...

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...

Cystic Fibrosis Opportunistic Infections
3,228 wordsResearch Pseudomonas Aeruginosa Pseudomonas aeruginosa Research Paper Julie Johnson Pseudomonas aeruginosa is a versatile gram negative bacterium that grows in soil, marshes, and coastal marine habitats, as well as on plant and animal tissues. People with cystic fibrosis, burn victims, individuals with cancer, and persons infected with HIV are particularly at risk of disease resulting from Pseudomonas aeruginosa. Unlike many environmental bacteria, Pseudomonas aeruginosa has a remarkable capacit...
