Packing DNA

Eukariotic cells face a hard to picture space problem: to pack a 2 meter long molecule into a 6 microns in diameter sphere. Not only that, the cell must be able to pack and unpack this DNA locally in order to perform its functions.

A protein called Condensin has been long known to be related to the DNA packing process, but until last year, the way this protein worked was still a mystery. Prof. Cees Dekker has directed the research that has unveiled this secret. For us, non biologist it is hard to understand how important this is and its repercussion, but the fact that it has been published in Science gives us a hint. This work is a collaboration between TuDelft (Netherlands) and EMBL (Germany).

Thanks to this research we know now how Condensin traps the DNA and uses its ring to drag the DNA forming a loop. Together with the people of TuDeflt we made this video explaining the motor function of this protein.

We are particularly proud of the music piece… hope its epicity expresses both the importance of the finding and the pride we’ve felt when they let us participate in the project.
