MacBooks are made from aluminium)‚ cooking utensils‚ transportation (aircraft‚ rockets and cars mainly because of their high strength-to-weight ratio)‚ packaging‚ water treatment‚ street lighting etc. Aluminium is the most abundant metallic element in the lithosphere‚ thought to be 7.5 to 8.1%‚ it is rare to find it isolated. Due to its high reactivity it forms a high-energy bond with oxygen‚ thus making it difficult to extract. Therefore it has to be refined form alumina‚ using the Hall-Heroult

Extraction of DNA from Cheek Cells Gene Smith February 29th 2013 INTRODUCTION DNA‚ deoxyribonucleic acid‚ is the genetic material of every living organism and is found in the nucleus of eukaryotic cells. DNA is often called the ‘blueprint for life’ because it contains the necessary information to carry out all the living processes of the cell (1).The purpose of this lab was to extract DNA from human cheek cells. The isolated DNA could be used inmapping or sequencing‚ PCR‚ crime scene investigation

crystallization process using the preferred recrystallizing solvent‚ water. The crystallization process was when crude acetanilide was placed in hot water bath and was cooled after in an ice bath which would then yield to the formation of crystals of pure acetanilide. The percentage yield form the crude acetanilide was 94.59%. The percentage recovery of the experiment was 46.43%. INTRODUCTION Organic compounds that are synthesized in laboratories or isolated from natural recourses are often

1) Using tweezers remove individual plants from the soil and remove the roots with scissors. Measure the weight of each individual and place in a 1.5 mL microfuge tube. Place this tube directly into liquid N2 to freeze plant tissue. 2) Remove tubes from the liquid N2 and quickly grind the plant tissue with a pestle. Add 300 L of Methanol 1%HCl and continue to grind the plant tissue. Allow extraction to occur overnight in a dark refrigerator. 3) Add 200 L Milli-Q H20 to each tube. Next
