Other than coding for polypeptides, are there any genetic information is carried by DNA?

If you consider microRNAs, rRNAs, and tRNAs, then yes. These elements come from a gene and are not polypeptides. There's also a whole host of regulatory information encoded in DNA which controls how genes are expressed (promoters, 3'UTRs, introns, LCRs, etc).

even the introns are said to have regulatory functions on gene expression.don't forget the biological clock.
