There are six different types of interemdiate filemtsn there are 70 genes that are going to enode for them ad there are 210 cell types and that means that eveyr cell type is going to have three IF’ tupes.
The basic uni fo the intermeidat eiflmetsn are gonig ot be dimers and the dimer sa reoiigng ot hav ea n hea dn c tial and absically waht thsu eman is that hte tial is going ot be large eht emieor so is oign go tha velaoha and hte laphs a ar eoigng ot bidnt ogeher and in order to two they form a coiled coil and cbaisllhte the ends ar eoging o t be there. and another thing is hta thtey dont bind no ncueltoides no gtp nao atp and they are na euqilrbium stat ebeuca sety eodnt need enrgy in order ot bind anything. and so they are quelbrium anotehr thing is tha thte idmer ar e oging ot bidntg oa tnoerh edimer ot form a tetra mae r and tetram mer is going ot make proitfialme and the orotie four of those are oigng o make a protifbirl an four of htse ar eoging ot bto make a pintemridal fiemtsn and they ahve no polarity becaus eht c’s are oging ot be opost eo feahcother when the hbidn to another trame and this wa seeen in the imunog godl iwth tht ogld parti and abitto and . they are stbale and storna nother things i sthat ther helix is goin to be one turn is 7 amin acids na dht e7th is oging othave a miano acid reisid eand theya re going ot be hdryopbo abd in this hcase they are giong to hid inteh coild coil alpha helix. ya ata they can be psotinve and negati veos they hav eno poalri ta dhtey are goingto be ocnsived th eoppst eantiparlla ei soging ot be ocnsided

okei recap of all of topic nine that i just learned okei so baciall all u gotta know is that mciubtuels are oging ot be form dimers , each dimer is going ot have a monomer and yte monoerm si going to be alpha tubulian dnbeta tubulina dn baisclly wat this means si thtis
okei recap os basiclaly wer areoing goitn to hav etes lapha nd beta na dhte alpoha is stu in the gtp form and beta is abel the o chdyaliz en awhne they dbing toehte hter eaer iogn tobe seam shte b is usual nec to the sme abut hwen the a is nex to the b it is oging ot be the seam and so thritheen proriflemtns ar eoging ot make a mcirubtuel. mcirbuels are hollow in the middle and they ahve
mcb tuels and
they are going ot be in naimal sclel sna idn filclia nf algaellum ‘
aials calle s aroeng ot have mcibtutel orngvaiizng centers that are goign to be cnetoms na naimsla are going ot have basal bodies and sothat mena sthath in metaphse theya re going to be reongized into spindle fibers/ in cilis the negativ end is anchored and is going to bind to the basalbody and then the plus is going to grwo out and then the the plus is going to be toward the cilia anf lgaleluym the cilia dn glanneul is going to be the stuff that is going to bind stuff and move stuff oug.
anywho so when the dimer is going to bidn ot the plus cap it is going to bind in the gpt ofmr and when hdyrlzo aand until it hdrylzoyes it isi gogn to realse form the gd until it si fully relased from the poluemr it cannt ofall off frmomerm
