During anaphase where do microtubules shorten
WebAnaphase . During anaphase the microtubules shorten so much that the sister chromatids start to pull apart. The chromatids can only come apart if the proteins that are linking them together (cohesion proteins) are cleaved. WebWhich of the following statements about microtubules during anaphase is TRUE? Those attached to chromosomes shorten, while those that are unattached elongate. Both attached and unattached microtubules elongate at first and then shorten. Both attached and unattached microtubules shorten.

WebDuring anaphase the microtubules shorten so much that the sister chromatids start to pull apart. The chromatids can only come apart if the proteins that are linking them together (cohesion proteins) are cleaved. The pulling will also cause the cell to elongate as the sister chromatids are pulled to opposite sides of the cell in preparation to ...

WebAug 7, 2024 · Anaphase: During anaphase, the centromere splits, allowing the sister chromatids to separate. The kinetochore spindle fibers shorten, allowing for 46 of the newly- freed chromatids to be dragged to one end of the cell and the remaining 46 chromatids to be dragged to the opposite end of the cell.
