Nerve cells communicate with with one another by fiddling local 
potassium to sodium ion ratios. It changes the voltage difference across 
the cell-to-cell junctions. The signals can propagate fairly fast.

https://nba.uth.tmc.edu/neuroscience/m/s1/chapter03.html

"In fact, the propagation velocity of the action potentials in nerves 
can vary from 100 meters per second (580 miles per hour) to less than a 
tenth of a meter per second (0.22 miles per hour)."

DNA doesn't come into it (or at least not directly).

Science daily was suggesting that regular cells use a similar sort of 
system for communicating with their near neighbours. Why this would be a 
"hidden communication system" escapes me. If nobody looked for it, it 
wouldn't have to be "hidden" to be unknown.
