Dust of Genes

A comet swings around the sun.
As the comet heats up,
it will spew dust.

It is flexible, in slight ways
to better accommodate the kind
of repetitive history tools.—

An opportunity to explore the body’s markers:
The genes that are switched on or off.
—An attempt to understand the unknown.
