"When densely packed, long molecular chains, such as chromosomes, in living cells can crawl past their neighbours, computer simulations and theoretical modelling suggest. An individual polymer molecule can wriggle out of a pack of similar molecules."
Research combining computer simulations and theoretical modeling reveals that long molecular chains, including chromosomes found in living cells, possess the ability to crawl past their neighboring molecules when densely packed together. This phenomenon suggests a previously underappreciated mechanism of molecular movement within crowded cellular environments. The findings indicate that individual polymer molecules can navigate through tightly packed arrangements of similar molecules, potentially explaining how biological macromolecules maintain necessary mobility and function despite spatial constraints within cells.
