Difference between G1 Phase and G2 Phase are in tabular form below –
No. |
G1 Phase |
G2 Phase |
Definition |
||
1. | In the cell cycle, a period from the end of cell division to the DNA replication beginning, this phase is known as G1 phase. | In the cell cycle, a period from the DNA replication completion to the cell division beginning, this phase is known as G2 phase. |
Sister chromatids |
||
2. | In the G1 phase, sister chromatids are absent. | In the g2 phase, sister chromatids are present. |
Phase |
||
3. | In the interphase, G1 phase is the first phase. | In the interphase, G2 phase is the last phase. |
Spindle formation |
||
4. | In this phase, spindle formation does not occurs. | In this phase, spindle formation occurs. |
Requirement |
||
5. | In the G1 phase, the metabolism and the growth requires proteins and RNA. | In the G2 phase, the preparation of cell for division requires proteins and RNA. |
Organelles number |
||
6. | In this phase, organelles number remains the same. | In this phase, organelles number increases. |
