Everything is Ok with your RNA!
The 3 bands are the rRNA bands which are the major part of Your
prepÖ(Eucaryotic Ribosomes have 5S, 5.8S, 18S and 28S rRNA resulting 3 bands).
If this bands are sharp, you can be sure your RNA is not degraded.
The normal smear of all the other RNAs should be nearly invisible, whereas a
thick smear in the upper part of your gel, over the two heavier bands , is a
sign for DNA contaminationÖ.
