It is essential for cells to control precisely which of the many genes of their genetic material they use. This is done in so-called transcription factories, molecular clusters in the nucleus. Researchers of Karlsruhe Institute of Technology (KIT), Friedrich-Alexander-Universität Erlangen-Nuremberg (FAU), and Max Planck Center for Physics and Medicine (MPZPM) have now found that the formation of transcription factories resembles the condensation of liquids.

Our DNA is so tightly packed that it fits into the nucleus of every cell. Our genetic library is the source of products such as RNA and proteins. The first step in the production process is called transcription. The process behind how the areas in the nucleus where transcription occurs are created was not fully understood until recently.
