Phenylalanine Hydroxylase Pah Enzyme Phenylalanine Hydroxylase Pah Pku
899 wordsPhenylketonuria is one of the commonest inherited disorders - occurring in approximately 1 in 10, 000 babies born in the U. S. It occurs in babies who inherit two mutant genes for the enzyme phenylalanine hydroxylase (PAH). This enzyme normally breaks down molecules of the amino acid phenylalanine that are in excess of the body's needs for protein synthesis. Because we inherit two copies of the gene for the enzyme, both must be defective to produce the disease. A laboratory test that measures ho...

Polar Regions Magnetic Field
612 wordsPioneer 10 was launched in 1972 and flew within 81, 000 miles (130, 000 kilometers) of Jupiter on Dec. 3, 1973. The probe revealed the severe effects of Jupiter's radiation belt on spacecraft. Pioneer 10 also reported the amount of hydrogen and helium in the planet's atmosphere. In addition, the probe discovered that Jupiter has an enormous magnetosphere. Pioneer 10 was launched toward Jupiter on an Atlas rocket in 1972. After reaching the planet in late 1973, it made the first close-up photogra...

Genetically Engineered Restriction Enzymes
2,958 wordsGenetic Engineering Discuss the applications and techniques involved in genetic engineering. Consider the advantages and disadvantages of this approach. Genetic engineering is an umbrella term that can cover a wide range of ways of changing the genetic material the DNA code in a living organism. This code contains all the information, stored in a long chain chemical molecule, which determines the nature of the organism. Apart from identical twins, genetic make-up is unique to each individual. In...

This disease is the most common genetic disorder amongst Caucasians. Cystic fibrosis affects about one in 2, 500 people, with one in twenty five being a heterozygote. With the use of antibiotics, the life span of a person afflicted with CF can be extended up to thirty years however, most die before the age of thirteen. 1 Sinc...

Circuit Under Test 555 Timer Ic Logic
466 wordsLOGIC PROBE SUMMARY Logic Probe is one of the basic troubleshooting tools for common electronic logic circuits (TTL circuits). Almost all video game circuit boards are built using TTL chips. These chips will occasionally fail and the Logic Probe is a tool that affords us a look into what may be failing, and it s a very handy measuring device used to determine output logic levels. The 555 timer IC is used in this circuit. The 555 timer IC uses power supply voltage from about 5 volts up to 18 volt...

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...
