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.
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

DNA on abstract background
RNA And DNA concept as a deoxyribonucleic acid or a ribonucleic acid as biological molecules as a symbol of the evolution of life and genetic sequencing.
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.
