What conditions is most likely to promote the growth of centrosome-nucleated microtubules?

The conditions which will most likely lead to promote the growth of centrosome-nucleated microtubules is if there is the presence of a GTP-cap on the (+) - end of the microtubule.

Answer: Six are most common conditions that can promote teh growth of centrosome-nucleated microtubules.

Explanation:

The most common conditions that will promote growth areas;

1. A very high cytosolic concentration of ATP, alpha-tubulin in cytosol.

2. Concentration of cytosolic GTP bound alpha/beta tubulin heterodimers which promotes the formation of a GTP, cap at (+) (-) end.

3. The presence of capping protein at (+) - end of the microtubule.

4. Instant hydrolysis of GTP on each alpha beta heterodimer that becomes added.

5. The concentration of cytosolic GTP, such as bound alpha-beta tubulin heterodimers which is little bit low that a GTP-cap cannot form at (+) - end.

6. The microtubules can only grow at their (-) end, not at their (+) - ends
