During the G ₁ -phase of cell division

Options

  1. ARNA and proteins are synthesised
  2. BDNA and proteins are synthesised
  3. Ccell prepares for M-phase
  4. Dcell undergoes duplication

Correct answer

A. RNA and proteins are synthesised

Step-by-step solution

Cell division has two phase : (a) Karyokinesis : Division of nucleus (b) Cytokinesis : Division of cytoplasm. Karyokinesis also consists of two phase : (i) Interphase is a resting phase and consists of G ₁, ~S and G ₂ -phase. array |c|l| Phase & Activities G ₁ & RNA and proteins synthesis takes place S & DNA replication takes place G ₂ & array l Damaged DNA is repaired and division of centrosomes takes place array array (ii) M-phase represents the phase of actual division.
