    A Hirt DNA Extraction is an isolation of all extrachromosomal DNA in a mammalian cell. The Hirt extraction process gets rid of the high molecular weight nuclear DNA, leaving only low molecular weight mitochondrial DNA and any viral episomes present in the cell.

    Purpose: To attempt to extract DNA from different organisms, while at the same time learning the DNA extraction process. Hypothesis: We will be able to successfully extract DNA from the onion, both types of wheat germ, and the Escheria coli.

    1.) contamination from organism (either celld debris of foriegn DNA). 2.) if doing phenol-chloroform extraction, wrong ratio could be used and hence no formation of layers. 3.) salt concentrations/alcohol concentrations wrong and hence no DNA or no DNA precipitation. good luck.
