Temporal coding in transcription factor levels

“The researchers…have studied transcription factors, the signalling molecules inside cells that activate or deactivate genes. They found that the strength of the signal is less important than the dynamic frequency pattern that is used.
…
‘The timing of the repeating signal is essential for its interpretation. It seems that cells may read the oscillations in level of transcription factors in a similar way to Morse code.’
