Circadian Rhythm essay Essays

Circadian Rhythm essay Essays Circadian Rhythm essay Paper Circadian Rhythm essay Paper Circadian Rhythm   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The article, Circadian clock-protein expression in cyanobacteria: rhythms and phase setting, is an interesting scientific breakdown of a phenomenon that connects a certain type of bacteria to the timekeeping ways of other organisms. The article begins with a basic explanation of the biological evidence that they have gathered, but later goes on to expand its explanation to include lots of data to support the conclusion. In this article, charts, graphs, and unlimited data are presented in an effort to shed a comprehensive light on the circadian rhythms that are present.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The basic premise behind the theory presented in this article is that cyanobacteria have a time keeping system that help them run more efficiently than other forms of bacteria. The explanation centers on three different genes, aptly named kaiA, kaiB, and kaiC. These three genes are the primary reasons why the circadian clock system exists within the eukaryotic bacteria. Research within this article indicates that while only a few mutations of these genes exist, any deletion of the entire segment will cause widespread circadian characteristics.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   There are many different variables that affect this rhythmic method in bacteria. One of those things was light, as the article is quick to point out. The variances between the different genes are relevant in the data that is presented, especially the two charts that show how the genes reacted to being put in the presence of constant sunlight. In addition, the later part of the article addresses how different variables like different proteins can stop the induction of the gene, KaiC. The article finally came to the conclusion that the KaiC genes were much more rhythmic when not in the presence of constant light. In fact, darkness actually helped promote the clock-protein expression.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The article closes by stating some conclusions which are up for discussions. The basic premise presented in the conclusion has to do with the conditions under which oscillation is possible. For the three different genes, different constant conditions are necessary, and the article shows that KaiA is different than KaiB and KaiC genes.
