Mitochondrial Dna

a: Mitochondrial dna ~
b: twisted pearl necklace

What: DNA structure is like a twisted pearl necklace. Of course this analogy can only be taken so far. Pearls are generally homogenous in term of size and shape. The base pair sequence in DNA will vary considerably. The picture in the link is good visual initiation.

Dna Testing As Biochemcial Geneology

a: Mitochondrial dna testing ~
b: maternal biochemcial geneolgy

What: As note just about every where, mammals, human beings can trace their maternal lineage by having their mitochondrial DNA sequenced. This DNA does not cross-over with male DNA and therefore its sequence shows much lower variability than nuclear DNA that has been recombined with paternal DNA. So a comparison of an individuals DNA to other's DNA can give a hint about how closely they may be related, on the mother's lineage.

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.
