Novel structural determinants of single-channel conductance in nicotinic acetylcholine and 5-hydroxytryptamine type-3 receptors.

abstract：:Sister-chromatid cohesion, thought to be primarily mediated by the cohesin complex, is essential for chromosome segregation. The forces holding the two sisters resist the tendency of microtubules to prematurely pull sister DNAs apart and thereby prevent random segregation of the genome during mitosis, and consequent a...
