[Microbiology] high molecular plasmid DNA

Hello everyone

Does anyone know why in some cases we see (in an 0,8% agarose gel)  
plasmid DNA higher than chromosomal DNA?
I know that there are very large plasmids but it is possible to exist  
a plasmid bigger than the chromosome? I thought it wasn't possible.
I thought that is a characteristic of the separation of the agarose  
gels but if this is the case, how can we explain it?

Looking forward to hear from you something
Best wishes
