1. When cell in S phase is fused with cell in G1 phase, the cell of G1 phase is stimulated to proceed back to S pahse. Stage 1 matches with 2nd cell\'s nucleus is activated to go prematurely, into DNA synthesis. This is because G1 is premature stage and enter back to S pahse to continue the synthesis of DNA. 2. When cell in S phase is fused with cell in G2 phase, the cell of G2 phase has no effect of S pahse on it. Stage 2 matches with 2nd cell\'s nucleus does not respond. This is because G2 cell contains all things provided by S phase. 3. When cell in M phase is fused with cell in S phase, the cell of S phase undergo chromatin condensation and chromosomes are visible with single chromatid. Stage 3 matches with 2n cell\'s nucleus undergoes chromatin condensation, giving visible chromosomes with single chromatid. This is because, S pahse is synthesis phase and the synthesized DNA is condensed and only one chromatid of each chromosome is visible. 4. When cell in M phase is fused with cell in G1 phase, The cell of G1 phase undergo chromosome condensation and chromatin damage. Stage 4 matches with, 2nd cell nucleus undergo chromosome condensation causing massive chromatin damage. This is because, the G1 pahse is preparatory phase of cell division and M phase is mitotic phase containing disassembly of chromatids and deacetylation of histone proteins. Solution 1. When cell in S phase is fused with cell in G1 phase, the cell of G1 phase is stimulated to proceed back to S pahse. Stage 1 matches with 2nd cell\'s nucleus is activated to go prematurely, into DNA synthesis. This is because G1 is premature stage and enter back to S pahse to continue the synthesis of DNA. 2.

1. 1. When cell in S phase is fused with cell in G1 phase, the cell of G1 phase is stimulated to
proceed back to S pahse. Stage 1 matches with 2nd cell's nucleus is activated to go prematurely,
into DNA synthesis. This is because G1 is premature stage and enter back to S pahse to continue
the synthesis of DNA.
2. When cell in S phase is fused with cell in G2 phase, the cell of G2 phase has no effect of S
pahse on it. Stage 2 matches with 2nd cell's nucleus does not respond. This is because G2 cell
contains all things provided by S phase.
3. When cell in M phase is fused with cell in S phase, the cell of S phase undergo chromatin
condensation and chromosomes are visible with single chromatid. Stage 3 matches with 2n cell's
nucleus undergoes chromatin condensation, giving visible chromosomes with single chromatid.
This is because, S pahse is synthesis phase and the synthesized DNA is condensed and only one
chromatid of each chromosome is visible.
4. When cell in M phase is fused with cell in G1 phase, The cell of G1 phase undergo
chromosome condensation and chromatin damage. Stage 4 matches with, 2nd cell nucleus
undergo chromosome condensation causing massive chromatin damage. This is because, the G1
pahse is preparatory phase of cell division and M phase is mitotic phase containing disassembly
of chromatids and deacetylation of histone proteins.
Solution
1. When cell in S phase is fused with cell in G1 phase, the cell of G1 phase is stimulated to
proceed back to S pahse. Stage 1 matches with 2nd cell's nucleus is activated to go prematurely,
into DNA synthesis. This is because G1 is premature stage and enter back to S pahse to continue
the synthesis of DNA.
2. When cell in S phase is fused with cell in G2 phase, the cell of G2 phase has no effect of S
pahse on it. Stage 2 matches with 2nd cell's nucleus does not respond. This is because G2 cell
contains all things provided by S phase.
3. When cell in M phase is fused with cell in S phase, the cell of S phase undergo chromatin
condensation and chromosomes are visible with single chromatid. Stage 3 matches with 2n cell's
nucleus undergoes chromatin condensation, giving visible chromosomes with single chromatid.
This is because, S pahse is synthesis phase and the synthesized DNA is condensed and only one
chromatid of each chromosome is visible.
4. When cell in M phase is fused with cell in G1 phase, The cell of G1 phase undergo
chromosome condensation and chromatin damage. Stage 4 matches with, 2nd cell nucleus
undergo chromosome condensation causing massive chromatin damage. This is because, the G1
