B-chain pentamer and A-chain subunit (green), 3D cartoon and Gaussian surface model, white background
Bacteria pathogen - 3d rendered microbiology image. Illustrate of Lactobacillus Bulgaricus Bacteria, Microbacterium Tuberculosis Bacteria (MTB). Medical research, health-care concept. SEM (TEM) scanning view
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.
background
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.

Photomicrograph of head of brine shrimp, Artemia salina. Live specimen. Wet mount, 10X objective, transmitted brightfield illumination.
The glucagon like peptide-1 receptor (GLPr) is a G proteincoupled receptor (GPCR) that mediates the action of GLP-1, a peptide hormone. The activated receptor  has a strong effect  on the management of type 2 diabetes mellitus and obesity, including glucose homeostasis and regulation of gastric motility and food intake.
Abs Virus - 3d rendered image like colorized scanning electron micrograph. Scene showing virus (yellow)  emerging from infected cell.\nConcept of coronavirus that’s causing a global pandemic. Covid-19, Sars-cov-2 alpha, betta, gamma, delta, lambda variant, 2019-nCoV, Coronavirus.\nSEM, TEM, hologram view.
Biological protein and molecule, 3d rendering. 3D illustration.
DNA and biotechnology concept
Chain of amino acid or bio molecules called protein - 3d illustration
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.
CRISPR-CAS9 (3d structure), a gene editing complex from Streptococcus pyogenes. CRISPR are segments of prokaryotic DNA containing short, repetitive base sequences.
