Some DNA sequences appear multiple times in the genome. Here, an RNA guide probe labels repetitive regions in the nucleus of a Xenopus laevis sperm. University of California, Berkeley, researchers have discovered a much cheaper and easier way to target a hot new gene editing tool, CRISPR-Cas9, to cut or label DNA.

This is an example of hierarchical folded package of globule. A group of researchers from the Lomonosov Moscow State University tried to address one of the least understood issues in the modern molecular biology, namely, how do strands of DNA pack themselves into the cell nucleus. Scientists concluded that packing of the genome in a special state called "fractal globule", apart from other known advantages of this state, allows the genetic machinery of the cell to operate with maximum speed due to comperatively rapid thermal diffusion. The article describing their results was published in Physical Review Letters.

Pharmaceutical sciences researchers at Washington State University have discovered a protein's previously unknown role in cell division.
