Liver Fluke Section under light microscope with white background
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.
DNA A-T Pair
Backgrounds of Bacteria and Mold under the microscope in Lab.
A molecular model of Amyloid protein fibrils. Formed when mis-folded proteins self-assemble into fibrous sheet structures, they are found in the brains of sufferers of Alzheimer's disease and may be implicated in causing the disease.
Dna structure on science background. 3d illustration
Blastomycosis is a fungal infection caused by inhaling Blastomyces dermatitidis spores. If it involves only the lungs, it is called pulmonary blastomycosis. Only about half of people with the disease have symptoms, which can include fever, cough, night sweats, muscle pains, weight loss, chest pain, and feeling tired.
3D cartoon and Gaussian surface models, chain id color scheme,  PDB 2iw2, white background
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.
orange: RNA primer; red: RNA template; light blue: proofreading riboexonuclease; mid blue: helicase; dark blue: RNA directed RNA polymerase; violet: non structural proteins (NSPs).
Shiny artificial molecular structure in many colors. Horizontal composition, isolated on black background.
