    Not completely true. It is a bit less than 2 bits, due to its replication
    chains, and the presence of insertion points where cross-overs are possible.
    But the effective code is a bit more complex than just the ATCG system, as
    some studies have demonstrated that the DNA alone has no function out of its
    substrate, whose nature influence its "decoding".

    There are some extra pieces of information that are not coded directly in
    the DNA, and the DNA itself has a 3D structure which cannot be modeled
    completely with just this alphabet (try computing the position of sulfurs
    and oxidations only from this chain!).

    Research on DNA solves this problem by isolating active subchains of the DNA
    whose behavior does not depend significantly on the substrate. The DNA is
    splitted by "locus" points where variation can occur. And not all of the DNA
    is actively coding useful information; large fragments are simply there to
    consolidate its structure, or to recover from replication damages.

    In fact you can determine much more things from ARN fragments than from ADN
    itself. Simply because ARN is not only the replication of ADN, but also the
    result of its structuration in the substrate, with which it will help
    synthetize proteinic chains. Other information are also contained in the
    mediators that help transform the ARN information into proteins. Some of
    these mediators are sometimes external to the cell, or may come from
    parasitic agents (bacteries, virus), or live in synbiotic condition with the
    cell that need this pollution to live itself. Suppress those parasitic or
    synbiotic agents and the DNA alone will not allow the cell to survive...
