See more pictures of alternative fuel vehicles. You've probably heard about fuel cells. In 2003, President Bush announced a program called the Hydrogen Fuel Initiative (HFI) during his State of the Union Address.
Phenol-Chloroform Extraction. Purpose: Phenol-chloroform extractions are done when you need to purify DNA from a solution that also has proteins. The DNA will dissolve in the aqueous layer, and everything else will go into the non-aqueous layer.. Phenol:chloroform. 1  Add one equal volume of phenol:chloroform:IAA (found in 4C in room 263) to DNA solution. 2  The phenol:chloroform solution has two layers â be sure to take the bottom layer!!! 3  Mix gently; spin for 5 minutes at max speed. 4  Remove aqueous layer (top layer) to a new tube.
DNA extraction. DNA (DeoxyriboNucleic Acid) is a long stringy molecule that can be extracted from any biological material such as living or conserved tissues, cells and virus particles.A number of basic procedures are carried out to isolate and purify DNA.NA extraction.
