Question

Explain the mechanism in which the spindle fibers connect to the kinectochore on the centromere, please?

Answer 1

The kinetochore forms in eukaryotes, assembles on the centromere and links the chromosome to microtubule polymers from the mitotic spindle during mitosis and meiosis.
when the chromosomes are in the middle during dat time spindle fibres are also present there and when it comes in contact with chromosomes the clutch them with the help of kinetochore

Answer 2

how does it 'clutch' onto the spindle fibers?

Answer 3

luk just imagine spindle fibres has hook and kinetochore has knot in which spindle fibre comes n get attached by it

Answer 4

oh, so it's a hook-and-clutch system? thanks!

Answer 5

no there is no system like dat i m jst giving n example

Answer 6

There are a family of proteins called cohesins that hold the microtubules of the spindle to the kinetochore. Take a look at this:

Answer 7

Thank you. I do prefer an explanation in terms of protein functions.
