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).

Neuroendocrine carcinoma well differentiated (carcinoid) rectum with immunostain synaptophysin
Nucleosome, molecular model. 3D illustration. The nucleosome consists of a DNA double helix wrapped around a core of histone proteins.
Inside protein molecule
Human cell on scientific background. 3d illustration
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.
DNA close-up, DNA Molecule Model, DNA Strands, DNA animation
Chromosome structure with telomeres at the ends.
mRNA (multicoloured strand) is decoded in a ribosome to produce an aminoacid chain, that folds into a protein (red). tRNA (dark violet) molecules carry single aminoacids that are incoporated into the growing chain.
Liver Fluke Section under light microscope with white background
3D cartoon and Gaussian surface models, PDB 2j0D, 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.
Nucleosome structure. Structure of an oligonucleosome, showing the packaging of DNA in chromosomes. 3D illustration.
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.
IG-g like Antibodies are attacking a foreign protein.
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.
Bacterial multidrug efflux pumps (E-CmeB) expel antibiotics from inside the bacterium (bottom): ciprofloxacin (yellow), chloramphenicol (violet), ampicillin (red).
Chain of Amino Acid. Proteins consist of one or more chains of amino acids called polypeptides
3D cartoon and Gaussian surface models, PDB 7las, chain id color scheme, white background
DNA A-T Pair
Backgrounds of Bacteria and Mold under the microscope in Lab.
Bacteria pathogen - 3d rendered microbiology image. Illustrate of Lactobacillus Bulgaricus Bacteria, Microbacterium Tuberculosis Bacteria (MTB). Medical research, health-care concept. SEM (TEM) scanning view
Dna structure on science background. 3d illustration
Photomicrograph of rotifer. Rapidly rotating cilia at top of head, internal organs visible. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination.
Immunotherapy of Alzheimer's disease: Monoclonal antibody (light blue) bound to an amyloid beta peptide (orange), that is aggregated to amyloid beta fibrils, which build up amyloid plaques.
A molecular model of Human Insulin. Isolated on black.
