This physical separation of different chromosomes is important for the ability of DNA to function as a stable repository for information, as one of the few times chromosomes interact is in chromosomal crossover which occurs during sexual reproduction, when genetic recombination occurs.
Denne fysiske adskillelse af forskellige kromosomer er vigtig for DNA'ens evne til at fungere som et stabilt informationsarkiv, da en af de få gange kromosomer interagerer er ved overkrydsning, der sker under kønnet formering, hvor genetisk rekombination finder sted.
