Bacterial multidrug efflux pumps (E-CmeB) expel antibiotics  from inside the bacterium (bottom): ciprofloxacin (yellow), chloramphenicol (violet),  ampicillin (red).
A model of a transcription factor binding to a strand of DNA. Transcription factors are proteins which bind to specific sequences of DNA, enabling and controlling the copying of genetic data.

Proliferating cell nuclear antigen (PCNA) is a DNA clamp that acts as a processivity factor for DNA polymerase δ in eukaryotic cells and is essential for replication. PCNA is a homotrimer and achieves its processivity by encircling the DNA, where it acts as a scaffold to recruit proteins involved in DNA replication, DNA repair, chromatin remodeling and epigenetics. 3D cartoon and Gaussian surface models, chain instance color scheme, based on PDB 3wgw, white background.

The algae species Pediastrum boryanum under the microscope.
A conceptual image of an abstract network of multi-coloured organic strands arranged in a non regular pattern all connected together in a complex manner. The network is made from smaller multi-coloured squares and polyhedra, in vivid colours against a pastel toned background. Shows background and foreground elements to the structure.

After dopamine binding, the dopamine receptor changes his shape and binds the inactive G protein.The G protein expels its GDP molecule replacing it by GTP. and falls into two pieces. The Galpha subunit binds to and activates the enzyme adenylyl cyclase, which produces then cyclic AMP spreading a signal through the cell.
