How proteins read meta DNA code

Three-quarters of the DNA in evolved organisms is wrapped around proteins, forming the basic unit of DNA packaging called nucleosomes, like a thread around a spool. The problem lies in understanding how DNA can then be read ...

A new, dynamic view of chromatin movements

In cells, proteins tightly package the long thread of DNA into pearl necklace-like complexes known as chromatin. Scientists at EPFL show for the first time how chromatin moves, answering longstanding questions about how its ...

Why some genes are highly expressed

The DNA in our cells is folded into millions of small packets, like beads on a string, allowing our two-meter linear DNA genomes to fit into a nucleus of only about 0.01 mm in diameter. However, these molecular beads, called ...
