Synopsis

DNA is often described as a code, a sequence, a set of instructions. But long before it is any of these things, it is a physical object—a charged, flexible thread moving through a landscape shaped by fields, ions, and boundaries. Its behavior is not defined by sequence alone. It is defined by the environment that surrounds it.

Inside the nucleus, that environment is intricate and ancient. Chromatin bends, softens, and confines the molecule in ways that encourage looping, folding, and long-range interactions. The electric field is never abrupt. The ionic gradients are never chaotic. The boundaries are never flat. Everything is curved, layered, and quiet. DNA responds to this world with a choreography that is both delicate and predictable.
