Why do cellsgo to all the trouble of coiling and shortening their cromosomes before they start to separate them?
Answers
Answer: Hope this help !
Explanation:
Look,
The genetic material (basically chromatin material)in our nucleus is like loose strands of threads (i.e in spireme state)) hence to be seperated in such a way there's High risk of tangling and inappropriate distribution
Whereas when they get highly coiled and compact they can easily be distributed
It is the same as seperating Tangled threads and some scattered pins......which would be easy?
Also to facilitate untangling during cell division they develop telomere at ends
As mitosis progresses, the microtubules attach to the chromosomes, which have already duplicated their DNA and aligned across the center of the cell. The spindle tubules then shorten and move toward the poles of the cell. As they move, they pull the one copy of each chromosome with them to opposite poles of the cell ,so they start coiling and shortening ....
