2. Identify the correct statement with regard to $G_1$ phase (Gap 1) of interphase.
[2020]
(a) Reorganisation of all cell components takes place.
(b) Cell is metabolically active, grows but does not replicate its DNA.
(c) Nuclear Division takes place.
(d) DNA synthesis or replication takes place.
Show Answer
Answer : b
Hints & Solutions
(b) During $G_1$ phase the cell is metabolically active and continuously grows but does not replicate its DNA. DNA synthesis takes place in $S$ phase. Nuclear division occurs during Karyokinesis. Reorganization of all cell components takes place in M-Phase. In some organisms, karyokinesis is not followed by cytokinesis as a result of which, multinucleate condition arises leading to the formation of syncytium.
