An alternative structure has been gaining momentum, however.

For two dimensions, in particular, this alternative structure would be a vector of pointers to vectors, one for each row.

In order for the transcribing polymerase to concomitantly capture the alternative structure, the time scale of the structural modulation must be comparable to that of the transcription.

Experimental evidence also supports this alternative structure.

Dozens of changes and adaptations to alternative structures to the original design followed.
