<span>The Rock Cycle is the process in which rocks are
formed, changed, and broken down. An igneous rock can either change into a
sedimentary or into a metamorphic rock; just the same that a sedimentary rock
can change into an igneous rock or metamorphic rock. Factors like heat, water,
and air can break and
form new types of rocks in a continuous cycle. <span>
<span>The rock
cycle never stops; it is a continuous process that occurs through time. A
mountain that is composed of<span> metamorphic rocks can easily be
washed away by streams and new sedimentary rocks can be formed through this
process. </span></span></span></span>
It is often useful for scientists to study a population of cells that are all at the same stage of the cell cycle.
<h3>Why the discovery of cyclins and cdks was enabled?</h3>
The discovery of cyclins and cdks was enabled by studying frog eggs that divided synchronously after fertilization; extracts from the embryos were thus representative of the cell-cycle stage at which the extract was made.
Researchers have devised means to synchronize asynchronous populations of cultured cells. for example, serum starvation deprives cells of mitogens and blocks cells in the g0/g1 phase of the cell cycle.
Therefore, It is often useful for scientists to study a population of cells that are all at the same stage of the cell cycle.
