Question 1 · NEET 2026 · Q101 · +4 / −1

Match List-I with List-II

List I (Phase of cell cycle)	List II (Activity)
P) $G_1$ phase	I) Actual cell division occurs
Q) S phase	II) Cell is metabolically active and continuously grows but does not replicate its DNA
R) $G_2$ phase	III) Synthesis of DNA occurs and the amount of DNA per cell doubles
S) M phase	IV) Proteins are synthesized while cell growth continues

choose the correct answer from the options given below:

Answer and explanation

Answer: (4)

In $G_1$ phase the cell is metabolically active and grows but does not replicate DNA; in S phase DNA is synthesised and the DNA per cell doubles; in $G_2$ phase proteins are synthesised in preparation for mitosis while growth continues; and in M phase the actual cell division takes place. This gives P-II, Q-III, R-IV, S-I.

Question 2 · Re-NEET 2026 · Q128 · +4 / −1
The correct sequence of adult cell cycle phases is ________.
Answer and explanation
Answer: (3)
Interphase runs G1, then S, then G2, and only then does the cell enter M phase to divide. The logic is that DNA must be replicated in S phase before the gap phase G2 allows the cell to check the copy and prepare for mitosis; dividing before replication would be fatal.

Question 3 · Re-NEET 2026 · Q131 · +4 / −1
Given below are two statements :

Statement I: Chromosomes are fully condensed at the end of prophase I.
Statement II: Meiosis I resembles mitosis.

In the light of the above statements, choose the most appropriate answer from the options given below :
Answer and explanation
Answer: (3)
Prophase I is the longest and most complex phase of meiosis, running through leptotene, zygotene, pachytene, diplotene and diakinesis; by diakinesis the chromosomes have reached maximum condensation, so Statement I holds. Statement II names the wrong division: it is MEIOSIS II that resembles mitosis, since sister chromatids separate and no pairing or crossing over occurs. Meiosis I is the reductional division, with homologues pairing, recombining and then separating - none of which happens in mitosis. NCERT Class 11, Cell Cycle and Cell Division.
Question 4 · NEET 2020 · Q25 · +4 / −1
Match the following with respect to meiosis and select the correct option.
List I
List II
P) Zygotene
I) Terminalization
Q) Pachytene
II) Chiasmata
R) Diplotene
III) Crossing over
S) Diakinesis
IV) Synapsis
Answer and explanation
Answer: (1)
Synapsis occurs in zygotene, crossing over in pachytene, chiasmata become visible in diplotene, and terminalization occurs in diakinesis. Thus P-IV, Q-III, R-II, S-I. Chapter: Cell Cycle and Cell Division.
Question 5 · NEET 2020 · Q65 · +4 / −1
Some dividing cells exit the cell cycle and enter vegetative inactive stage. This is called quiescent stage (G0). This process occurs at the end of
Answer and explanation
Answer: (1)
Cells can exit the cell cycle and enter the quiescent stage (G 0 ) at the end of the G 1 phase. Chapter: Cell Cycle and Cell Division.
Question 6 · NEET 2020 · Q69 · +4 / −1
Dissolution of the synaptonemal complex occurs during
Answer and explanation
Answer: (2)
The synaptonemal complex dissolves during diplotene, leading to the separation of homologous chromosomes while they remain connected at chiasmata. Chapter: Cell Cycle and Cell Division.
Question 7 · NEET 2020 · Q75 · +4 / −1
Identify the correct statement with regard to G1 phase (Gap 1) of interphase.
Answer and explanation
Answer: (2)
During the G1 phase, the cell is metabolically active and grows, but DNA replication does not occur. Chapter: Cell Cycle and Cell Division.

List I	List II
P) Zygotene	I) Terminalization
Q) Pachytene	II) Chiasmata
R) Diplotene	III) Crossing over
S) Diakinesis	IV) Synapsis
