Question

ln which phase, proteins for spindle fibre formation are synthesized?

• A. G${}_1$ phase
• B. G${}_2$ phase
• C. S phase
• D. Anaphase

Answer 1

The correct option is B G${}_2$ phase

G${}_2$ phase is second growth phase. It occurs after synthesis phase in a typical cell cycle. In the G${}_2$ phase synthesis of tubulin protein which is the major component of microtubules takes place. The spindle fibres are made of microtubules. So, the correct answer is option B.
