Re: Cell Division Questions

... either way I don't think (d) is correct either I tried googling this and can't find an answer. Hopefully someone else can. In anaphase of mitosis kinetochores pull daughter chromosomes towards opposite poles of the spindle. I know that in late anaphase II the kinetochores detach from each other ...

Cell Division Questions

... is correct out of each question) Q1. The following list of events in the cell cycle is in the correct order: a) Chromosomes align at equator, kinetochores attach to spindle fibres, cytokinesis, new nuclear membranes form. b) Interphase, centrioles move to opposite poles, anaphase, chromosomes ...

What's the diff between spindle fibers & mitotic spindle?

... spindle fibers, mitotic spindle, AND microtubules the same thing? Also what is the difference between centro some , centro mere , centrioles and kinetochores? :? I learned back in middle school that the centromere is where the spindle fibers attach during Mitosis, however now all these other ...

The Fiber Disease

... to active centromeres of animal chromosomes and therefore is believed to be a component of the specialized centromeric nucleosomes on which the kinetochores are assembled. Here we report that CENP-A, highly purified from HeLa cells, can indeed replace histone H3 in a nucleosome reconstitution ...
