Introduction Extraction is a purification technique used in organic chemistry to separate compounds from a mixture of two or more compounds. There are three different extraction techniques: liquid-liquid extraction‚ solid-liquid extraction and chemically active extraction. All three types of extraction follow the same principle. Organic molecules dissolve in organic solvents and polar molecules dissolve in aqueous solvents. This phenomenon is observed because of the intermolecular forces between

It is gelatinous colloidal extractive of a red alga (as of the genera Gelidium‚ Gracilaria‚ and Eucheuma) used especially in culture media or as a gelling and stabilizing agent in foods.2 Agar-well diffusion method.3 It is a method of bioassay wherein wells are cut in seeded agar and the sample is then introduced directly into the wells. After incubation‚ the diameter of the clear zone around the well is measured and compared against zones of inhibition produced by the

Strawberries - Critical Essay Christopher Callaghan 12th September 2012 “Strawberries” by Edwin Morgan is a loving poem‚ which explores the wonders of human emotions such as love‚ lust and fear. The poet’s purpose in writing this piece was to educate the reader and to evoke emotions with poetic techniques. Morgan uses some extremely effective metaphors in this poem to describe his relationship with his partner: “We dipped them in sugar‚ looking at each other.” The sugar signifies that

(4) the advent of DNA profiling. 2. Describe the criteria for admissibility of scientific evidence as laid out in Frye v. United States. The court ruled that in order to be admitted as evidence at trail‚ the questioned procedure technique‚ or principles must be “generally accepted” by a meaningful segment of relevant scientific community. This approach requires the proponent of scientific test to present to the court a collection of experts who can testify that the scientific issue before the

Experiment 3 Liquid-Liquid Extraction Discussion The success of extracting each compound out of the solution can be seen in the IR graphs for each substance. For ethyl 4-aminobenzoate‚ the N-H‚ C=O and C-O are distinguishable in their proper wavenumber positions. The amino N-H stretch was found between 3224 cm-1 and 3423 cm-1. The C=O was found at 1681 cm-1 and the C-O was at 1280 cm-1. The IR for benzoic acid also displays its significant bonds‚ O-H and C=O. The O-H was between 2566 and

Six billion people around the world from every imaginable background with incredible diversity yet despite these differences are more connected to each other than you might think. In 2005 the National Geographic and IMB teamed up to draw people together and make people realise that we are all part of an extended family and that our DNA connects all of us by the one man‚ he is scientific Adam.

Compare and contrast the synthesis of the leading and lagging strands in DNA replication. • Explain how the genotype of an organism determines its phenotype. • State the central dogma of genetics and explain the roles of DNA and RNA in polypeptide

DNA molecules are very long. They wrap around proteins and wind tightly‚ forming structures called chromosomes. A human somatic (non-sex) cell has 23 pairs of chromosomes. Twenty-two pairs are autosomes‚ which do not differ between the sexes. The autosomes are numbered from 1 to 22‚ with 1 the largest. The other two chromosomes‚ the X and the Y‚ are sex chromosomes. The Y chromosome bears genes that determine maleness. In humans‚ a female has two X chromosomes and a male has one X and one Y. Charts

DNA testing has overthrown the way police collect evidence in a number of criminal cases‚ especially rape and murder and consequently had a large impact on many past cases. However there are many disadvantages to DNA testing‚ such as a challenge of accuracy‚ the costs of DNA testing and the possible misuse of DNA. The prospect of a national DNA database in Australia has been heavily criticised with complaints of invasion of privacy and stigma against those with terminal diseases. Deoxyribonucleic
