Genetic engineering is a complex field in which scientists use a range of molecular tools to make changes to DNA, the information center of cells. You might have heard of gene editing techniques such as CRISPR, TALENs, and even PRIME Editing.  But now researchers at Princeton University may have found a simple solution that can not just make DNA molecules bend and turn but also snap them together as desired.  Are chromosomes liquid or solid?  Ever since the discovery of the chromosome, researchers have wondered if the structure, made up of long strands of DNA coiled around proteins, behaves like a solid, liquid, or something in between.  This might seem like a question of curiosity alone. But delve a bit deeper into genetic disease and one realizes that the answer to how to treat them depends on knowing more about chromosome behavior.  Researchers at Princeton were keen to solve this mystery and developed a tool that could probe chromosomes to learn more about their mechanical properties.  Working with condensates Some …
