Gel Electrophoresis Restriction Enzymes
554 wordsDNA, Deoxyribonucleic acid, is a double stranded, helical nucleic acid molecule which determines inherited structure of a protein. The steps are made of bases: adenine, guanine, cytosine, and thymine. The sides are sugar and phosphate molecules. Restriction enzymes are enzymes that cut DNA at restriction sites, leaving fragments blunt or sticky. The restriction fragments are separated using a technique called DNA has a negative charge so when an electrical charge is applied it makes DNA move to ...

Dna Gel Electrophoresis Research
1,724 wordsThe main objective of this lab was to identify unknown plasmids by observation of their genotype and phenotype. We observed the plasmids phenotype by using it to transform bacteria. When the plasmid is in a bacterial host the antibiotic resistance gene can be expressed and impart resistance to the host. We also analyzed the genotype of the unknown plasmid by performing a variety of molecular genetic techniques such as predigestion, electrophoresis in arose gel, staining with ethidium bromide, an...

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...

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...

Favored Nation Nineteen Ninety
3,483 wordsWhat is the debate on weather or not China should retain favored-nation trading status all about? Is it really a decision on what is best economically for the United States, and China. Or is it: the issue of Chinese human rights violations and the fact that if the United States where to revoke the favored nation status of China it would have a profound negative impact on the U. S. economy alone. (+) Most-favored-nation trade status started in the United States as a version of the European prefer...
