Using DNA in Science and Technology DNA is the blueprint for life‚ it is found in the nucleus of cells on the chromosomes. It is found in many cell organelles‚ such as plasmids in bacteria‚ chloroplasts in plants‚ and mitochondria in both plants and animals. DNA helps us to perform many actions in solving crimes‚ and also helps us to do scientific studies that were not possible until recently. DNA has a double helix structure‚ its sugar phosphate backbone‚ made up of deoxyribose and a phosphate

Extraction and Analysis of Plasmid DNA from E. coli Cells Introduction A plasmid is an extra-chromosomal element‚ often a circular DNA. Since a plasmid is by definition an extra-chromosomal element‚ it cannot make use of any origin of DNA replication in a chromosome (BP site). Meaning that DNA synthesis within a plasmid depends on having an origin of DNA synthesis of its own. Plasmids are often found in bacterial cells‚ in which they are used as transfer agents for transmitting various antibiotic

the Extraction lab is to separate and purify benzoic acid‚ 2-naphthol‚ and naphthalene. These organic solids are purified by partitioning the solid in 2 immiscible solvents‚ diethyl ether and sodium bicarbonate or sodium hydroxide. II. Significance a. The significance of the Extraction lab is to purify Acetanilide benzoic acid‚ 2-naphthol‚ and naphthalene by determining the partition coefficient. This value is determined by dividing the solubility of the given solute in the extraction solvent

2mL level Detergent: DI: 2.6mL level CaCl2: 3.8mL level The results of the soap tests indicate an unsuccessful synthesis of soap. Minimal amount of foam was observed from any the tests. It was expected that foam would be presents in DI water‚ but decreased in CaCl2 or Trisodium because it makes the water a “hard water” and causes the soap precipitate‚ make it ineffective. As seen from the results‚ the synthesized detergent is effective in both soft (DI) and hard (with CaCl2) waters. When the
