Q. In which phase, proteins for spindle fibre are synthesized?
A) $G_{1}$-phase
B) $G_{2}$-phase
C) S-phase
D) Anaphase
Explanation
In $G_{2}$-phase of interphase stage of cll cycle, the proteins required for spindle formation are synthesized. In $G_{1}$-phase, enzymes required for protein and DNA replication are synthesized. In S-phase, DNA replication process takes place. In anaphase, chromosomes split longitudinally at the centromere.
