Mural seems to contain range (5)
I believe the answer is:
urals
'range' is the definition.
(mountain range)
'mural seems to contain' is the wordplay.
'to contain' says the answer is hidden in the clue (words from the clue contain the answer).
'URALS' can be found hidden inside 'mural seems'.
(Other definitions for urals that I've seen before include "mountain area" , "Mountains of west-central Russia" , "Mountain range in Russia and Kazakhstan" , "Russian mountain range" , "Mountains of Western Russia" .)
