"A free nucleotide is like a single base floating around without a partner. So there would be A's, T's, C's, and G's with noone to hold hands with. Can you tell me which bases always stay together? Super! A's and T's and C's and G's. So if the DNA has unzipped and there are bases hanging out by itself, what do you think those free nucleotides might do? I hope you said that a free nucleotide would come in and attach itself to the correct base. "
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
