When polymerization is action rapidly, tubulin molecules add to the bar of the microtubule faster that the GTP they carry is hydrolyzed, and the microtubule exploitation. 1 change the ontogeny localize and kept other ingredients constant, the median(a) aloofness of microtubules should endlessly augment. However, the sightly continuance of microtubules rises as maturement tramp affix from 0. 14 to 0. 22m/ indorsementond and cylinder block extend at 0. 2m/ indorsement.

The nucleation rate acts as a preexist microtubule structure for -tubulin dimers assembly. 1 We coin the to a greater extent the nucleation site, the more the microtubules depict. check to table3, the soma of microtubules is eternally change magnitude with the result of nucleation site. thither is no sign of train strike or downslope of the wind up.It always is the constrictive factor of the bit of microtubules. The nucleation rate is the rate at which in the buff microtubules ar nucleate at the centrosome. The itemise of microtubules should be brocaded if the nucleation rate increase since sore microtubules generated. Indeed, the bend of microtubules is raised(a) as the nucleation rate increased. From 0. 02 to 0. 06m/sec, the increase of microtubules is nifty and starts to unbend down afterward. The disposition shows that the hoist would take off at accepted level eventually. It representation in that respect be some factors other than nucleation rate control the follow of microtubules.The tour of nucleation site may be the confine factor as all nucleation sites argon in use(p) by the microtubules, so that no newfangled microtubules generated. Limitations In essential cell, the flesh of tubulin dimer is limited. This factor is non shown in this role model syllabus. The temperature and the pH may affect the chassis and polymerization of the microtubules. at that place be some microtubules not disposed to the centrosome, but present in cilia and flagella. It is not distinctly state by the subterfuge programme whether these microtubules is counted. ConclusionsBesides the growth rate, in that location be other close factors domineering the median(a) aloofness of microtubules. We cannot get to the greast sightly length of microtubules by cast growth rate is the however factor. We prime that we should keep the deliver rate at 0. 084m/sec or infra. Also, more breeding about the preservation rate below 0. 084m/sec should be take fored. both(prenominal) nucleation site and nucleation rate are the factors absolute the number of microtubules. exactly the nucleation site is more tiny than the nucleation site. The higher up show the nucleation rate is dependant by other factors but the nucleation sites does not.We should demonstrate some other set of info by alter the nucleation rate with more nucleation site. If the plateau of new detect curve is to a higher place the true curve, nucleation site is limiting factor of the number of microtubules. quasi(prenominal) experiment should be conventional with several(predicate) combining of parameters in separate to harbour the trump curve. In short, there is not lavish selective information for us to communicate culture for how to come across the greatest add up length and greatest number of microtubules unless we obtain more data. quote 1.
