B-chain pentamer and A-chain subunit (green), 3D cartoon and Gaussian surface model, white background
orange: RNA primer; red: RNA template; light blue: proofreading riboexonuclease; mid blue: helicase; dark blue: RNA directed RNA polymerase; violet: non structural proteins (NSPs).
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.
Microalgae under microscopic view, green algae, cyanobacteria, phytoplankton, diatom, algae mix collage background
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.

3D cartoon and Gaussian surface models, PDB 2vtb, white background.
plant Leaf of Nerium indicum T.S. under light mircoscope with white background
p53 (blue) tagged with ubiquitin (yellow) is degraded into small peptides by a proteasome (violett). p53 prevents cancer formation and acts as a guardian of the genome. Mutations in the p53 gene contribute to about half of the cases of human cancer.
Bacteria pathogen - 3d rendered microbiology image. Illustrate of Lactobacillus Bulgaricus Bacteria, Microbacterium Tuberculosis Bacteria (MTB). Medical research, health-care concept. SEM (TEM) scanning view
Licmophora sp. algae, marine and freshwater diatom under microscopic view. Genus of benthic, photosynthetic and epiphyte diatom
The three-dimensional structure of proteins is represented in a variety of conformations. This image is based on the ribbon structure of a protein. It is suitable for biology notebooks and book covers.\nThis image has not been created by AI.
Botulinum toxin (3d structure) which prevents the release of the neurotransmitter acetylcholine from axon endings at the neuromuscular junction. Infection with the bacterium causes botulism.
chromosome,Human genome concept
3D cartoon and Gaussian surface models, chain id color scheme, PDB 7t3a, white background
Computational tomography image of the abdominal and pelvic regions.
Bacterial multidrug efflux pumps (E-CmeB) expel antibiotics  from inside the bacterium (bottom): ciprofloxacin (yellow), chloramphenicol (violet),  ampicillin (red).
Photomicrograph of two rotifers. Rapidly rotating cilia at top of heads, internal organs visible. Live specimen. Wet mount, 10X objective, transmitted brightfield illumination.
Haematococcus pluvialis green and cyst algae under microscopic view, empty space - haematocyst, active and resting cells, strong antioxidant astaxanthin
Artificial molecular structure in many colors. Horizontal composition, isolated on white background.
Thyroid cancer: Microscopic image of Metastatic papillary carcinoma of thyroid. Reactive change. Lymph node carcinoma.
DNA Helix - 3d rendered image. Genetic research concept. Complex spiral structure illustration. Medical, science, genetic biotechnology, gene cell, chromosome idea. DNA strands on dark background . Science nanotechnology.
Secreted by Staphylococcus aureus, this toxin binds with the outer membrane, with subsequent oligomerization of the toxin monomers to form water-filled channels. These are responsible for osmotic phenomena, cell depolarization and loss of vital molecules (v.gr. ATP), leading to cell death. 3D cartoon model in two purpendicular projections, chain id color scheme, based on PDB 3anz, white background.
Liver Fluke Section under light microscope with white background
From left to right: the NMDA and  AMPA receptors transport calcium cations into neurons after being activated by the neurotransmitter glutamate and  the GABA receptor (right) transport chloride anions after the activation by gamma aminobutyrate. PDB entries: 6wht,  3kg2, 6d6u
