tsükliin

Tsükliin is a term used in Estonian to refer to a cycle or a period. It can apply to various contexts, including natural cycles, biological processes, or recurring events. For instance, in biology, it might refer to the cell cycle, which is a series of events that take place in a cell leading to its division and duplication. This cycle involves distinct phases such as growth, DNA replication, and mitosis.

The concept of tsükliin can also be used in relation to astronomical phenomena, such as lunar cycles or planetary orbits. These are predictable, repeating patterns governed by gravitational forces. In a more general sense, tsükliin can describe any sequence of events that repeats itself over time. This might include seasonal changes in weather, the daily cycle of day and night, or even recurring social or economic patterns. The understanding of tsükliin helps in predicting future occurrences and analyzing trends.
