A. | Cells are metabolically active and proliferate | i. | \(G_2 phase\) |
B. | DNA replication takes place | ii. | \(G_1 phase\) |
C. | Proteins are synthesised | iii. | \(G_0 phase\) |
D. | Quiescent stage with metabolically active cells | iv. | S phase |
A. Cells are metabolically active and proliferate: This occurs during the G1 phase of the cell cycle, where the cell grows and prepares for DNA replication. A-II
B. DNA replication takes place: This occurs during the S phase (synthesis phase). B-IV
C. Proteins are synthesized: Protein synthesis occurs throughout the cell cycle but is particularly active during the G1 and G2 phases. C-I, and since G1 has already been assigned then it should be G2 making it C-I
D. Cells at the non-dividing stage with metabolically active cells: This describes the G0 phase, a non-proliferating stage where cells remain metabolically active but do not proliferate. D-II
A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :
