Scientists take atomic look at a protein complex that grants access to our DNA

To transcribe the information contained in our genes or to repair the dozens of breaks that occur daily in our DNA, our enzymes must be able to directly access the DNA to perform their functions. However, in the cell nucleus, this access is limited because the DNA strands are often tightly coiled and packed around proteins like threads around spools.

Researchers reveal how acetylation regulates centromere dynamics, chromosome segregation and mitotic progression

Cell division produces new cells, which underpin life proliferation and development. Mitosis is the shortest and the most dynamic phase of the cell cycle. During mitosis, chromosomes are evenly distributed between the two daughter cells, preserving the integrity of the genome.
