In the molecular-level world of ion channels—passageways through membranes that carry signals in a cell's environment and allow it to respond—researchers have debated about the role of a small piece ...

Human life hinges on the ability of our cells to cram six feet of DNA into a 10-micron nucleus—equivalent to fitting a mile of string inside one green pea. But stuffing genes into cramped quarters is ...

Figure 2: Deletion of the NegC domain of the Snf2h catalytic subunit does not substantially affect linker DNA length sensing by the ACF complex. Figure 3: The AutoN domain of Snf2h and the nucleosomal ...

A new study finds that proteins known as linker histones control the complex coiling process that determines whether DNA will wind into long and thin chromosomes, made up of many small loops, or short ...
