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.

Fluconazole is an antifungal medication used to treat fungal infections like candidiasis and mycosis. Due to genetic mutations in the active site (red), fluconazol can't bind anymore to the target enzyme, the lanosterol 14 alpha-demethylase, while the substrate lanosterol (violet) can still bind and be transformed in ergosterol (blue). Ergosterol plays an important structural role in the regulation of membrane fluidity and permeability. Source: PDB entry 5esf.
