NEETBotanyCell Cycle and Cell Division
Cell Cycle Phases DNA Content A. G1 phase 1. DNA content returns to 2n after cytokinesis B. S phase 2. DNA content doubles from 2n to 4n C. G2 phase 3. 4n, ready for cell division D. M phase 4. 2n, no DNA replication has occurred
Options
- AA-1; B-3; C-2; D-4
- BA-2; B-1; C-3; D-4
- CA-4; B-2; C-3; D-1
- DA-1; B-2; C-4; D-3
Correct answer
C. A-4; B-2; C-3; D-1
Step-by-step solution
G1 phase: DNA content is 2n, no replication has occurred. S phase: DNA content doubles from 2n to 4n. G2 phase: DNA content is 4n, ready for cell division. M phase: DNA content returns to 2n after cytokinesis.
