I am doing some DNA electrophoresis from marine yeast using the following 
restriction enzymes: Alu I, Eco RI, Hinf I, Kpn I, Pst I. I am using 2% 
agarose gel. At least in Alu I and Eco RI I can see some patterns. 
However, the background is so intense that I can't distinguish very well 
the pattern. The smear is lightly less intens than the bands. 

Is it because I have both DNAs (genomic and mitochondrial)?

How can I have more clear gels in a way to take nice pictures?

I am really concerned about this because my thesis is almost finished 
but I can't have nice imagens from this gels. If you have some ideas 
about what to do please e-mail me to:
