CRISPR-Cas9 gene editing technology
Chain of amino acid or bio molecules called protein - 3d illustration
A ball-and-stick plus ribbons molecular model of the hormone Orexin, also known as Hypocretin.  Orexin is involved in the regulation of the sleep/wake cycle and it stimulates apetite, wakefulness and energy expenditure. It has been linked with Alzheimer's disease.  Isolated on white.

DNA Molecule: a 3D illustration of the double helix structure reflecting the genetic code. This 3D illustration is a visualization of the DNA molecule showing its characteristic double helix structure. The model reflects the major components of DNA such as the nitrogenous bases (adenine, thymine, guanine, and cytosine), sugars, and phosphate groups that together form the genetic code. This illustration can be used for educational purposes, scientific publications or medical advertising to demonstrate the complexity and beauty of the molecule responsible for heredity and the development of life on Earth.
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.
Endosomes - 3d rendered image of Endosomes are membrane-bound organelles. They are parts of endocytic membrane transport pathway.  Endomembrane system in cells. Bilayer Lipid Membrane. Abstract medical illustration. Microscopic view. Microbiologic research concept.

3d helix chromosome or Dna structure, technology science background. 3d render illustration
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.
The calcitonin gene related peptide (yellow) binds to its receptor (blue) on neurons and smooth muscle cells of cerebral blood vessels, activating a signal cascade through G-proteins (dark blue) in this cells that  leads to a dilatation of the blood vessels (vasodilatation).

Wireframe double helix DNA
Nucleosome structure. Structure of an oligonucleosome, showing the packaging of DNA in chromosomes. 3D illustration.
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.
