Question

State the main difference between g1 and g2 phase. Plzz tell me the correct answer​

Answer 1

Answer:

During the G1 phase, the cell shows first growth by copying organelles and making the molecular building blocks which are necessary for later steps. During the G2 phase, the cell shows the second growth by making proteins and organelles and beginning to reorganize its contents in preparation for mitosis.

Answer 2

Difference # G1 Phases:

1. It is the first sub stage of interphase.

2. Available factors determine its fate, entry in Go, differentiation or continuity of cell cycle.

3. Cell organelles do not increase in number.

4. Cell grows in size but growth of nucleus is little.

5. It synthesizes RNAs, proteins and other biochemical for cell growth and subsequent replication of DNA.

Difference # G2 Phases:

1. It is the last sub stage of interphase.

2. There is very little choice for the cell except to proceed further in cell cycle.

3. Cell organelles increase in number.

4. Both cell and nucleus grow in size.

5. It synthesizes RNAs, proteins and other biochemical for spindle formation and M- phase division.

(*Important difference: One significant difference between growth phases is that the first growth phase is about cell growth while G2 is about cell division.)
