Why is a chromosome with two centromeres (adicentric chromosome) unstable?

HOW DO WE KNOW? how chromosomes are distributed during cell division, both in dividing somatic cells (mitosis) and in gamete- and spore-forming cells (meiosis). We found many opportunities to consider the methods and reasoning by which much of this information was acquired. How do we know that mitotic chromosomes are derivedfrom chromatin?
If a cell is deficient of Separase, how would this affect the chromosome dynamic movement during mitosis and meiosis? Explain.

Beginning with the G1 phase of the cell cycle, describe the levelof compaction of the eukaryotic chromosome. How does thelevel of compaction change as the cell progresses through thecell cycle? Why is it necessary to further compact the chromatinduring mitosis?
Models of higher-order compaction suggest that thenucleosomal fiber is supercoiled into a shorter but widerfiber. __________-proteins anchor this fiber to thechromosome scaffold, forming loops that are thengathered together to condense DNA even more
