Question

In a cell, al the cell organelles became double but the condensation of chromatin has stalled. In this cell, which check point is activated?
S/G,
G/M
Both GIS and S/G,
Gils​

Answer 1

Answer:

a) S/G - is the correct answer.

Answer 2

The answer is S/G. This is a major checkpoint.

Explanation:

• The decision of the cell to divide occurs in G1 phase. If a does not want to divide it will enter into quiescent phase.
• When the conditions changes, the cell can enter back into G1 phase.
• G1 to S transition in the cell cycle is called Restriction point or checkpoint. This is a major checkpoint.
• Once the cell crosses the restriction point, it is destined to complete the cell cycle.
• The cell cycle is regulated by a cyclin-dependent protein kinase.
• Cyclins are proteins that activate protein kinases to regulate the eukaryotic cell cycle.
