Inside protein molecule
Nucleosome, molecular model. 3D illustration. The nucleosome consists of a DNA double helix wrapped around a core of histone proteins.
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.
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
Structure of novel coronavirus spike receptor-binding domain (pink) complexed with its receptor ACE2 (blue), surface modeel, white background
This computer-generated image vividly illustrates the invasive Group A Streptococcal bacteria, as they would appear under a microscope. This visual representation helps to understand the microscopic world of Group A Streptococcus and its potential to cause serious diseases.
CRISPR or Endonuclease enzyme, 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.
A model of a nucleosome. Isolated on black.
Conjugal of DNA to primary antibodies with protein G and linker for multiplexed cellular targeting: 3D rendering
TRPV1 is an ion channel that senses heat, regulates the body temperature and contributes to pain sensation. Source: PDB entry 5is0.

DNA methylation is the main epigenetic modfication of DNA. Methylation (white spot) can change the activity of a DNA segment. The DNA methyl transferase I (light blue) transfers a methyl group from S-adenosyl methionine  (red) mostly to cytosine bases of the human DNA. Source: PDB entry 3pt6
Molecular Structure. Science background. 3D Render
3D cartoon model, secondary structure color scheme, PDB 5lb8, white background
A model of a molecule of arginine, an amino acid. Amino acids are the building blocks of proteins and have many functions in metabolism. In particular, Arginine has an important function in the immune system, wound healing and cell division.
