organic chemistry, model of the protein molecule - illustration of a biological particle

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.

$Mitochondria are important organelles in the cell. It is directly involved in our drive to live. ATP production by mitochondria is the source of energy.\nAnd even if you are not familiar with biology, mitochondria are widely known and are a persistent image of cells and cell biology.\nIt is no exaggeration to say that it is the concept of the existence of the details of the living body.\nThis image was not created by AI.$

The amyloid beta peptide (light blue) is a component of the amyloid precursor protein, which is bound to a cell membrane. The gamma secretase enzyme cuts the free form, that aggregates to amyloid plaques. Source: PDB entries 2beg, 1mwp

c-Myc and Max transcription factors bound to DNA. 3D illustration. Atoms shown as spheres with conventional color coding.

Squash preparation of onion root tip cells stained to reveal chromosomes, Bright field illumination, light microscopy. This image was taken with the X40 objective lens. Depth of focus is extremely low at this magnification. Smaller apertures give greater depth of focus, but image quality deteriorates and resolution is greatly reduced. The aperture in this image was optimised for contrast and resolution. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.
