Cell Cycle And Cell Division Question 1

Question: Match List I with List II:

List I List II
A. M Phase I. Proteins are synthesized
B. G₂ Phase II. Inactive phase
C. Quiescent stage III. Interval between mitosis and initiation of DNA replication
D. G₁ Phase IV. Equational division

Choose the correct answer from the options given below :

(1) A-II, B-IV, C-I, D-III

(2) A-III, B-II, C-IV, D-I

(3) A-IV, B-II, C-I, D-III

(4) A-IV, B-I, C-II, D-III

Show Answer

Answer: (4) A-IV, B-I, C-II, D-III

Explaination-

G1, S and G2 phases are the sub-phases of interphase of the cell cycle

G1 (gap 1) phase- first phase of interphase, interval between mitosis and cell division, cell remains metabolically active

S (synthesis) phase- cell makes an extra copy of DNA by replication

G2 (Gap 2) phase- proteins are synthesised in preparation for mitosis

Quiescent stage (G0 phase)- cell remain metabolically active do not proliferate unless called on to do so depending on the requirement of the organism
