comment What's the difference between protein and DNA behaviour during agarose gel electrophoresis?
I'd recommend to simply focus it on DNA and ignore proteins. You should also find out what equipment is available, you need a gel electrophoresis chamber (and they are different for agarose and PAA), power supply, the gel material itself (+ APS and TEMED for PAA), buffer, loading dye, something to stain the DNA or protein, and in the case of DNA also a UV lamp.

comment What's the difference between protein and DNA behaviour during agarose gel electrophoresis?
As already mentioned, you don't use agarose for proteins, they're pretty much exclusively run on polyacrylamide gels, typically as an SDS-PAGE. I've never seen anyone run an agarose gel of a protein.

comment Can we say that microevolution and macroevolution is fundamentally the same thing over different time scales?
This question about the difference between macro- and microevolution might be of interest.

comment Why is uracil used in RNA rather than thymine?
@fredsbend the 2'OH of the ribose and the methyl group of thymine are pretty far away from each other, there is no obvious way they would affect each other.

comment DNA degradation rate
@JunkDNA One important source of DNAses and RNAses when isolating nucleic acids are the cells/tissues themselves from which the DNA/RNA is isolated. Pure nucleic acids in an appropriate buffer are very stable, in my experience RNA samples can be stable for years at 4°C or even above (small RNAs with stable structures).
