Question) How is such a long polymer packaged in a cell?

Dear student,                     
​Please find below the solution to the asked query  

There is large amount of DNA in our cells which creates a packaging problem. So, in order to maintain a high degree of organisation the DNA is folded. DNA helix combines with a group of eight histone molecules (histone octamer) to form structures called nucleosome. It can coil the DNA tightly to reduce their size so as to fit them in the cell.
