Extraction The first stage of processing is the extraction of the cane juice. In many factories the cane is crushed in a series of large roller mills: similar to a mangle [wringer] which was used to squeeze the water out of clean washing a century ago. The sweet juice comes gushing out and the cane fiber is carried away for use in the boilers. In other factories a diffuser is used as is described for beet sugar manufacture. Either way the juice is pretty dirty: the soil from the fields‚ some small

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

we already comprehend that there is a possibility complex organisms evolved from unicellular organisms during the Archean Eon‚ there is no explanation to how unicellular life came about. There are many theories to explain the origin of life‚ one of which stated that life came from deep-sea hydrothermal vents which provided chemical compounds to generate energy via chemosynthesis. Another theory claimed that life came from electric sparks based on the Miller-Urey experiment. This experiment stimulated

understand that there’s a God who is a savior (Wheatley). Wheatley wrote‚ “On Being Brought from Africa to America” during the 1700s.

Knowledge can be gained through various means‚ the most important being reading the books. Experinced is also one of the important factor to gained the indepth knowledge. There has been always a controversy between the two about which one gives richer and broader view of knowledge. I personaly feel that this two are interrelated‚ in the sense one follows the other. Knowledge gained through reading the books is of no use unless and untill we implement it in our practical life. Implementing the knowledge

Grignard Synthesis of Triphenylmethanol from Benzophenone Purpose: The purpose of this experiment was to synthesize the tertiary alcohol triphenylmethanol from a Grignard reagent‚ phenyl magnesium bromide. The Grignard reagent was synthesized from bromobenzene and magnesium and then reacted with benzophenone to produce triphenylmethanol. It was important that water be excluded from the reaction‚ in order to prevent the formation of benzene. The reaction of phenyl magnesium bromide and benzophenone
