Question

Consider the given cellat metaphase-I stage undergoing normal meisois.

Which of the following gametes will not be formed from this cell?

a)
b)
c)
d)

Correct answer is option 'D'. Can you explain this answer?

Answer

If you carefully look at the picture, small arms are overlapping on each other So there will be change in colour of small arms and when you see the larger arms they have already exchanged information, so there will be no change in color

Answer

D

Answer

Only small part of the arms will get overlapped during crossing over,' not the complete arm'.

Answer

Cell Cycle Phase for Mitotic Division Preparation:

G Phase:
- The correct phase of the cell cycle when the cell prepares for mitotic division by rapidly growing and synthesizing proteins is the G phase.
- The G phase stands for the 'Gap' phase and is further divided into G1 and G2 phases.
- During the G1 phase, the cell grows and carries out its normal functions.
- In the G2 phase, the cell continues to grow and prepares for cell division.
- The G phase is crucial for the cell to accumulate the necessary resources and energy for the upcoming mitotic division.

Cell Growth and Protein Synthesis:
- During the G phase, the cell undergoes significant growth as it prepares for division.
- The cell synthesizes a wide range of proteins that are essential for various cellular processes, including DNA replication, cell cycle regulation, and cell division.
- Proteins involved in spindle formation, chromosome condensation, and cell signaling are synthesized during this phase.
- The cell also replicates its organelles and increases its overall size to ensure that both daughter cells receive an adequate amount of cellular components during division.

Importance of G Phase:
- The G phase plays a crucial role in ensuring that the cell is adequately prepared for mitotic division.
- By synthesizing the necessary proteins and growing in size, the cell can successfully complete the division process and maintain genomic integrity.
- Any abnormalities or deficiencies during the G phase can lead to errors in cell division, potentially resulting in genetic mutations or cell death.
In conclusion, the G phase of the cell cycle is essential for preparing the cell for mitotic division by promoting growth and synthesizing a wide range of proteins necessary for successful cell division.
