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.
Article Summary: DNA extraction is the process in which DNA is isolated from other cellular components through certain procedures. It has its applications in forensics.... DNA extraction is a procedure of isolating the DNA from other cellular components for the molecular or forensic analysis.Usually a machine is used to extract DNA from the cell that is called as Bead Beater. It breaks the cell and extracts the DNA from it.el Box is another machine which separates the sequences of DNA in the gel. An electric current is used for this purpose. In the end, centrifugation separates the DNA from the solution through spinning. Purpose of DNA Extraction:- Extraction of DNA is an important step in the diagnosis use.
