What is the role of cyclin-dependent kinases in the cell cycle?

Biology
1 answer:
jasenka [17]3 years ago
3 0

Answer:

They initiate various stages of the cell cycle.

Explanation:

Cyclins and cyclin-dependent protein kinases function to control  the cell cycle. A group of cyclins: the G1 cyclins, are synthesized during G1 phase and function  to activate CDPKs which initiate DNA synthesis at the G1/S checkpoint. The cell fails to  progress to S phase if there is no sufficient synthesis of G1 cyclins. After a cell passes through  this point, the G1 cyclins are degraded, allowing for another group of cyclins: the M cyclins  to be synthesized. M cyclins activate a second group of CDPKs which allow  the cell to pass the G2/M control point and into mitosis.

Based on the concept of the global conveyor belt, what happens to ocean water as it moves from Antarctica to the equator?
marta [7]

What happens to the ocean water as it moves from Antarctica to the equator is : ( B ) It becomes less dense and rises to the surface.

<h3>Concept conveyor belt </h3>

The conveyor belt is a system of oceans which transports water and propel deep current of water bodies across the globe based on the differences in water densities.

As the ocean water moves from the Antarctica to the equator the cold ocean water mixes with the warm ocean water at the equator, which makes the water less dense and rises to the surface.

Hence we can conclude that What happens to the ocean water as it moves from Antarctica to the equator is  It becomes less dense and rises to the surface.
