Polymers As Pearl Necklaces......
a: Mutagen ~
b: a black pearl in a pile of white pearls
What: There are many analogies floating around about polymers. The pearl necklace is a pretty good one. Polymers, both synthetic and natural, are composed of monomers that bind together to form a polymer; this is like a single pearl ear-ring combining with other pearls to form a necklace. DNA is a polymer made of nucleotide monomers. The monomers can be changed during DNA replication by chemical agents known as mutagens. This process is like being in a necklace factory with a big pile of pearls being made into necklaces. Except, thrown in with those white pearls, are an occasional black pearl that's the wrong type. The black pearl changes the appearance of the necklace the way a mutation changes the "LOOK" of a strand of DNA

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.
