To activate the kinases, cyclins connect to them. The activity of cyclin-dependent kinases changes with cyclin concentration. At the G2 phase, Cyclin and a Cdk unite to start mitosis (M phase). This mixture produces MPF (maturation-promoting factor), which encourages the cell to continue mitosis through the M phase. The cyclin is broken down at the G1 phase, and the Cdk is recycled.
<h3>What about cyclins?</h3>
- A family of regulatory proteins known as cyclins manages how the cell cycle develops.
- Cyclins cause the phosphorylation of cyclin dependent kinases (CDKs), which regulate the cell cycle.
- A target protein will attach to a complex made up of a cyclin and a CDK, and the complex will phosphorylate the protein.
- Cyclins collaborate with an enzyme family known as the cyclin-dependent kinases to control the cell cycle's activities (Cdks).
- A Cdk that is not bound to a cyclin is inactive, but when it is, it becomes a functioning enzyme that can alter target proteins.
- By phosphorylating and inactivating target substrates, cyclins are the regulatory subunits of holoenzyme CDK complexes that control progression through cell-cycle checkpoints.
- Cyclin-dependent kinases (CDKs) are protein kinases that require a distinct subunit - a cyclin - that provides domains necessary for enzymatic action.
- The cyclins associate with various CDKs to offer specificity of function at various stages during the cell cycle.
- In response to various extracellular and intracellular signals, CDKs modify transcription and play significant roles in the regulation of cell division.

Answer:
Explanation:Flowing water creates energy that can be captured and turned into electricity.The most common type of hydroelectric power plant uses a dam on a river to store water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity.
<span>Controlled experiment is an experiment done under controlled conditions in which only one variable at a time is changed in order to isolate the results. An alternative to a controlled experiment would be a correlation study. A correlation study is a research method in which two variables are compared (what are the similarities and the difference between them). So, correlation study is a type of controlled experiment in which ove variable is changed and the dependence with another variable is analyzed.</span><span />
