Name the type of sugar guanine is attached to?

Its obviously, "Deoxyribose sugar or Ribose sugar".
Nitrogenous bases like, Adenine, Guanine, Cytosine and Thymine are attached to deoxyribose sugar.
Adenine, Guanine and Cytosine can also remain attached to "Ribose sugar".
But, in case of Ribose sugar, Thymine is Replaced by Uracil Nitrogenous Base.
Hope it helps :-)
