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.
