The ...

Plasmid-DNAgram, a variant of DNAgram, adopted the concept of DNAgram that linguistic information could be encoded on bio-molecular sequences. For example, a DNA restriction map of "BsiWI XhoI EcoRV DraI" could be regarded as a word, "word." Plasmid-DNAgram aims to do linguistic information processing in vivo. To demonstrate this purpose, we used the fused catalytic and regulatory subunits of P...
