Circadian Clock Essay

There are many ways in which scientists and researchers try to understand the molecular uniqueness and physiology of living organisms. One of these ways is the Circadian clock, this clock transfers the physiology and behaviors of mammalians into rhythms that are coordinated with the 24hr solar system. This system can be affected by environmental factors such as the food, temperature and parasites. The circadian rhythms play a role in gene expression to produce protein. Gene expression is displayed through the central dogma of (DNA RNA protein). How the clock work with the 24hr solar day is that it allows gene expression every 24hr to tell when a physiological process is most active. And any damage made to the DNA is more effective

The master clock in the body is in the suprachiasmatic nucleus (SCN) of the hypothalamus. According to the article the SCN contains approximately 20,000 neurons that make up the circadian network. And nearly all cells in the body contains a molecular clock, information is passed through the circadian clock similar to how message is passed from the senses by external stimuli and send to the brain for interpretation. The master clock receives the light from the retina and transfer it to the peripheral clocks through endocrine and systemic cues. The comparable structure of the molecular clocks throughout body allows them to maintain circadian

This shows the importance of how the peripheral clocks works along with the circadian clock to maintain normal functions in the body. In addition, Takahashi highlighted that to find out how transcriptional and posttranscriptional regulatory mechanisms determine circadian output was done by “quantifying budding transcripts relative to mature mRNAs, which showed majority of the changes in the circadian changes in MRNA resulted from posttranscriptional regulation.” (Takahashi, Green & Partch, 2014). Nevertheless, it is still not proven what factors contributes to the gene
