How does a bacterium pack a 1.5 millimeters long circular chromosome into a cylindrical container of just 2 micrometers long and 1 micrometer wide?
This is a question that has occupied microbiologists for decades, but like many questions surrounding chromosomes it is difficult to tackle experimentally because of the small size of the bacterium …
A microtubule-based molecular switch determines the orientation of cell divison in plant stem cells
In order to create an organ like the plant root from a single niche of pluripotent cells, plants must control the orientation of the division plane. If all divisions were transverse …
