We move now to consider a substantial simplification of representing micronuclear and intermediate genes. We shall use only the sequence of pointers in the order in which they appear in such a gene, obtaining in this way just a string of pointers. This yields the framework of legal strings, which is more abstract than the framework of MDS descriptors because different MDS descriptors may yield the same legal string. In this chapter we investigate the basic properties of the representation of the MDS structure by legal strings. In particular, we characterize those legals string that either correspond directly to realistic MDS descriptors or that can be signed so as to correspond to realistic MDS descriptors.
