The biological clock controlling circadian rhythms must ultimately depend on environmental cues.

  • The interaction of clock gene protein products forms the molecular basis for the production of the circadian rhythm.
  • Circadian rhythms are often entrained to pertinent ambient time signals, with light being the most significant one.
  • However, circadian rhythms will still be exhibited if there are no such time cues. The rhythmic expression of genes at the molecular level controls circadian rhythms at the organismal level.
  • The transcriptional feedback loop with posttranscriptional and posttranslational control is the foundation of the conserved architecture of these circadian clocks.
  • Circadian rhythms are therefore intimately related to day and night. The master clock can be influenced by various cues including exercise, social interaction, and temperature, but light has the greatest impact on circadian rhythms.
