      Do organisms with similar mole percent (G+C) have similar base sequence?

      Likely not. For instance, CGCACGCACT has the same G+C content as CCCCCGGAAT, but the sequences are very dissimilar. Extremely high very low C+G percentage constrains the range of possible sequence somewhat, but organisms have plenty of all four bases and therefore can have great variation in sequence.
