The same applies, regardless of whether the claimed invention is a "nucleotide" or a "probe".

(Case b)
When the position of one part of the DNA sequence on the structural gene cannot be recognized clearly in the prior application by a person skilled in the art on the basis of common general knowledge, an invention specifying the part of the DNA sequence is not substantially identical to the entire sequence, even if the entire sequence of a cloned structural gene is described in the specification of a prior application.

The same determination is made regardless of whether the invention is claimed as a "nucleotide" or a "probe".
