A ball and stick + ribbons model of Human Growth Hormone, also known as Somatotropin.
orange: RNA primer; red: RNA template; light blue: proofreading riboexonuclease; mid blue: helicase; dark blue: RNA directed RNA polymerase; violet: non structural proteins (NSPs).
Nucleosome, molecular model. 3D illustration. The nucleosome consists of a DNA double helix wrapped around a core of histone proteins.
Wireframe double helix DNA
Proteasomes are molecular machines for breaking down proteins called proteolysis, only target proteins that have been marked for destruction called ubiquitin to the target protein, 3d rendering

Epidermis. Electron microscope micrograph showing a keratinocyte of spinous layer. The epithelial cell has a polygonal shape, central nucleus with nucleolus, cytoplasm full of keratin filament bundles, and numerous dark desmosomes crossing the intercellular spaces.
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.

Lymphocytic myocarditis. Myocarditis is an inflammation of the heart muscle. Lymphocytic refers to the type of cell seen in the affected tissue. A lymphocyte is a type of immune function cell.
The DNA tetrahedron is designed to be mechanically robust; it consists of rigid triangles of DNA helices covalently joined at the vertices

Proteasomes are a large molecular machine that degrade unneeded or damaged proteins that have been tagged with polyubiquitin (yellow). The ubiquitin hydrolase (violet) detaches ubiquitin from the protein, that is unfolded and degraded into small peptides (bottom). Source: PDB entry 5GJQ
