How is such a long polymer packed in a cell
Web2 feb. 2024 · 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 … WebWhen joined together they will form different variations of polymer chains. A large number of paperclips, preferably of different size and colour. First take a set of paperclips all of the same size or colour. These all represent the same molecule. Joining them together shows how many of the same monomer can be used to form a long, polymer chain.

WebDNA is one of the stiffest natural polymers, yet it is also one of the longest molecules. This means that at large distances DNA can be considered as a flexible rope, and on a short scale as a stiff rod. Like a garden hose, unpacked DNA would randomly occupy a much larger volume than when it is orderly packed.
