Question
Match List I with List II :
| List-I (Phase of cell cycle) | List-II (Activity) | ||
|---|---|---|---|
| A. | $G_{1}$ phase | I. | Actual cell division occurs |
| B. | S phase | II. | Cell is metabolically active and continuously grows but does not replicate its DNA |
| C. | $G_{2}$ Phase | III. | Synthesis of DNA occurs and the amount of DNA per cell doubles |
| D. | M phase | IV. | Proteins are synthesized while cell growth continues |
Choose the correct answer from the options given below :
Options
A.A-IV, B-I, C-II, D-III
B.A-I, B-II, C-III, D-IV
C.A-III, B-IV, C-I, D-II
D.A-II, B-III, C-IV, D-I
Solution
Sol. [Key Concept: Matching biological terms]
During $G_{1}$ phase the cell is metabolically active and continuously grows but does not replicate its DNA. S-phase marks the phase during which DNA synthesis or replication takes place and amount of DNA per cell doubles.
During the $G_{2}$ phase, proteins are synthesised in preparation for mitosis while cell growth continues.
During M phase the actual cell division takes place.
