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.
A molecular model of the flavonoid Quercetin.  An antioxidant and anti-inflamatory, it is used as a nutritional suplement.  It is commonly found in many fruits and vegetables and is a significant chemical component of tea.  Isolated on white.
