a: Histone ~
b: cylinder

What: "Non-helical model is also useful for histone binding of DNA, but the difference between histone and protamine is as the guy differentiates, histone is globular protein and protamine is a beta sheet. What this means is protamine is like a fibril adjacent to DNA, but histone is like a cylinder and DNA is the coil that wraps around it. So even though DNA is non-helical and the strands do not turn around each other, double stranded DNA turns around the histone. "

a: Histone arginine methylation ~
b: a dimmer switch for gene activation


"Professor Knox has some early data to show that one epigenetic process called “histone arginine methylation” is involved in switching on the interleukin 8 gene. Histone arginine methylation is like a dimmer switch for gene activation. Different levels and positions of histone arginine methylation ‘fine tune' how active a gene is."

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.
