p53 (blue) tagged with ubiquitin (yellow) is degraded into small peptides by a proteasome (violett). p53 prevents cancer formation and acts as a guardian of the genome. Mutations in the p53 gene contribute to about half of the cases of human cancer.

The LDL-receptor (red) is a membrane protein found in almost every human cell. It binds to the apoprotein B100 from LDL-particles and mediates their internalization (endocytosis) in the cell. This occurs in almost all cells but mainly in the liver where it removes about 70 % of LDL from the circulation.

Photomicrograph of filamentous blue-green algae, Oscillatoria species. Each band along the stand is one cell. This filament is very short probably having recently parted from a longer one. Filaments are typically many times longer. This algae is mobile, it moves and twists through the water. San Francisco Bay, California, USA. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live specimen, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.
