I cannot answer that specifically but how about simply running a test 
sample of known-length dsRNA and an equivalent length DNA?  I could 
PREDICT that the RNA might run faster than DNA since it is carrying the 
extra electonegative OH groups or make the opposite prediction that since 
it is carrying the bulky, extra OH groups, the RNA will not move as 
quickly through the agar matrix.  Why not put the question to rest and do 
the test (unless someone here already has or knows the answer)?
