3D cartoon and Gaussian surface models, chain id color scheme, PDB 3omv, white background
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.
orange: RNA primer; red: RNA template; light blue: proofreading riboexonuclease; mid blue: helicase; dark blue: RNA directed RNA polymerase; violet: non structural proteins (NSPs).
A ball and stick + ribbons model of Human Growth Hormone, also known as Somatotropin.
Proteasomes are molecular machines for breaking down proteins called proteolysis, only target proteins that have been marked for destruction called ubiquitin to the target protein, 3d rendering
Inside protein molecule
CRISPR-Cas9 gene editing technology
Multicolored antibodies or immunoglobulin protein structures - 3d illustration
3D cartoon and Gaussian surface models, PDB 6vg8, white background
Immunoglobulin G (IgG) - 3d rendered image. Microbiology illustration  the structure of an antibody. The Y-shaped structure. IgG is the most common type of antibody. Hologram view. SEM.
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.
anaplastic thyroid carcinoma with heterologous differentiation (leiomyosarcoma)
DNA close-up, DNA Molecule Model, DNA Strands, DNA animation
Liver Fluke Section under light microscope with white background
DNA composed of two chains that form a double helix. DNA is a molecule inside cells contains genetic information responsible for the development and function of an organism.
DNA and biotechnology concept
A carboxypeptidase is a protease enzyme that hydrolyzes a peptide bond at the carboxy-terminal end of a protein or peptide. 3D cartoon model, secondary structure color scheme, PDB 2v77, white background.
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.
Bacterial multidrug efflux pumps (E-CmeB) expel antibiotics  from inside the bacterium (bottom): ciprofloxacin (yellow), chloramphenicol (violet),  ampicillin (red).
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.
DNA A-T Pair
Biological protein and molecule, 3d rendering. 3D illustration.
Chain of Amino Acid. Proteins consist of one or more chains of amino acids called polypeptides
3D cartoon and Gaussian surface models, chain id color scheme, PDB 7t3a, white background
Myxoid liposarcoma.  Myxoid/round cell liposarcoma, or MRCLS, is one of several types of liposarcoma. Liposarcoma is a rare cancer that grows in the cells that store fat in the body. MRCLS usually grows in the arms and legs. These tumors grow slowly, and they can spread to other parts of the body
Pathological phosphorylation (yellow) of Tau proteins (red-orange) leads to disintegration of microtubuli in the neuron axon an aggregation of the tau proteins. The transport of synaptic vesicles (orange-blue) is interrupted.
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 close-up, DNA Molecule Model, DNA Strands, DNA animation
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.
