Based on genetic information, organic
molecules control the entire work of the
cell. The acids, DNA and RNA,
are organic molecules that direct the
protein [?], and proteins in their
turn are the main responsible
for the diversity of cellular biological
tasks. In branes and within the
cell, some organic molecules act as
[?] receptors and signalers.

Proteins and [?] have an important
role in the communication between cells
and , acting as [?],
substances that transmit information at
a distance throughout the organism.
