Extract DNA from Anything Living |[pic] | |Introduction: [pic] Since DNA is the blueprint for life‚ everything living contains DNA. DNA isolation is one of the most basic and essential techniques in the study of DNA. The extraction of DNA from cells and its purification are of primary importance to the field of biotechnology and forensics. Extraction and purification of DNA are the first steps in the analysis and manipulation of DNA that allow scientists to detect genetic disorders‚ produce DNA fingerprints

Extraction of caffeine from tea bags ABSTRACT Caffeine extraction from the commercial tea leaves (Lipton Yellow Label Tea) that was done is multiple extraction. 4 tea bags were used in the experiment; tea leaves were weighed having 8.5333 grams. The leaves were boiled in a beaker with 150ml of water; the aqueous tea extract was transferred in a seperatory funnel mixed with DCM (20ml)‚ done thrice. The DCM layer was washed with 20ml 6M NaOH in the seperatory funnel; the organic layer was dried

keep you all. Amen. ABSTRACT The extraction of pectin from orange peels has been studied at different sample to solvent ratios‚ different PHs and with different extraction techniques using water. The amount of pectin extracted reduces as the PH increased. This research work is been carried out in order to determine the process condition that will result in high yield of pectin and residual oil extracted from orange peels using the methanol pre-treatment to extract orange

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

Isolation‚ purification and characterization of alkaloid caffeine from tea leaves Date Submitted: September 3‚ 2014 Abstract Caffeine is one of the main constituents of tea leaves. In this experiment‚ 0.0039 g of pure caffeine was isolated from tea leaves. This was done through solid-liquid extraction followed by multiple liquid-liquid extraction. Then crude material obtained was then purified by sublimation. The isolated caffeine was subjected to thin layer chromatography (TLC) together

Optimal Growth Conditions and Generation Time for E. coli Introduction The goals of these exercises were to determine the optimal growing condition and the generation time of E. coli. Materials and Methods Please refer to the lab manual for a complete list of materials. To determine the optimal growth condition for E. coli‚ we had to test the environmental factors that could affect the growth. We tested the relative growth of E. coli in the presence and in the absence of oxygen. The results

There has been much debate in recent years among politicians‚ military officials‚ and civilians on whether or not the U.S. should be fully withdrawn from Afghanistan‚ regardless of the country’s economic and military capabilities. There has also been a proposed timetable‚ which President Obama says is in effect and currently being executed‚ to have up to ninety percent of our military personnel out of the country by no later than 2014. It is imperative that we extract our forces out of Afghanistan

also ductile‚ making it a very useful metal. Aluminium readily makes alloys with copper‚ zinc‚ magnesium‚ manganese and silicon. Aluminium foil is 92-99% pure aluminium. Other uses of aluminium alloys include computers (all Apple 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
