Dna structure on science background. 3d illustration
Squash preparation of  onion root tip cells stained to reveal chromosomes,  Bright field illumination, light microscopy.  This image was taken with the X40 objective lens.  Depth of focus is extremely low at this magnification.  Smaller apertures give greater depth of focus, but image quality deteriorates and resolution is greatly reduced.  The aperture in this image was optimised for contrast and resolution. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.

Secreted by Staphylococcus aureus, this toxin binds with the outer membrane, with subsequent oligomerization of the toxin monomers to form water-filled channels. These are responsible for osmotic phenomena, cell depolarization and loss of vital molecules (v.gr. ATP), leading to cell death. 3D cartoon model in two purpendicular projections, chain id color scheme, based on PDB 3anz, white background.
