DNA mutation, a mutation is a change in a DNA sequence, mutations can result from DNA copying mistakes made during cell division.
In vitro bacterial culture
DOT1L methylates a ubiquitinated nucleosome with the DNA methyl transferase I (mid) transfers a methyl group from S-adenosyl methionine (red) mostly to cytosine bases of the human DNA. Two ubiquitin molecules (light blue, right) binding to a nucleosome. Source: PDB entry 6NOG, 3PT6, 7XD0DOT!
Close-up shot of a petri dish for checking an antibiotic in the laboratory.
3D cartoon and Gaussian surface models, PDB 1j7n, chain id color scheme, white background
Inside protein molecule
Nucleosome structure. Structure of an oligonucleosome, showing the packaging of DNA in chromosomes. 3D illustration.
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.

Bacterial multidrug efflux pumps (E-CmeB) expel antibiotics from inside the bacterium (bottom): ciprofloxacin (yellow), chloramphenicol (violet), ampicillin (red).
Abstract Lactobacillus Bulgaricus Bacteria - 3d rendered microbiology image. Medical research, health-care concept. SEM (TEM)scanning view
Proliferating cell nuclear antigen (PCNA) is a DNA clamp that acts as a processivity factor for DNA polymerase δ in eukaryotic cells and is essential for replication. PCNA is a homotrimer and achieves its processivity by encircling the DNA, where it acts as a scaffold to recruit proteins involved in DNA replication, DNA repair, chromatin remodeling and epigenetics. 3D cartoon and Gaussian surface models, chain instance color scheme, based on PDB 3wgw, 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.
