NEET 2020 · BiologyCell cyclePrevious Year Question

Identify the correct statement with regard to G1 phase (Gap 1) of interphase.

Answer: (A) Cell is metabolically active, grows but does not replicate its DNA. Answer: Cell is metabolically active, grows but does not replicate its DNA Solution: During G1, the cell is metabolically active and continuously grows but does not replicate its DNA.

  1. A.Cell is metabolically active, grows but does not replicate its DNA
  2. B.Nuclear Division takes place.
  3. C.DNA synthesis or replication takes place.
  4. D.Reorganization of all cell components takes place.

Correct Answer

(A) Cell is metabolically active, grows but does not replicate its DNA

Solution & Explanation

Answer: Cell is metabolically active, grows but does not replicate its DNA Solution: During G1, the cell is metabolically active and continuously grows but does not replicate its DNA. DNA synthesis/replication is the S phase, nuclear division is M phase, and major reorganisation of cell components is M phase — so those statements describe other phases, not G1. NCERT Reference: Ch 10, p.121, lines 37-39 — "the cell is metabolically active and\ncontinuously grows but does not replicate its DNA"
