"In essence, qPCR is like a copy machine with a counter. The "primers" select which pages (target) of the book (DNA) are copied and the counter keeps a running total of how many pages were copied (number of target genes in the sample)."
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.
