Aerial view of an airplane flying over Lake Magadi in the Great Rift Valley, Kenya. Lake Magadi is the southernmost lake in the Kenyan Rift Valley, north of Tanzania's Lake Natron. The Rift Valley contains a chain of volcanoes and many other lakes such as the Turkana, Baringo, Bogoria and Nakuru. During the dry season Lake Magadi is covered by soda and is known for its wading birds. During the rainy season, a thin layer of brine covers much of the saline pan that evaporates rapidly leaving a surface of salt that cracks. The lake is recharged by saline hot springs and is very rich in blue-green algae, which feed insects and massive flocks of lesser flamingos (Phoenicoparrus minor). Altogether it forms a very peculiar mineral and colour-rich landscape. Currently the area is inhabited by the cattle-herder Masai tribes, but the relics of many hominids have been found in the escarpments.

Aerial view of Lake Magadi Lake in the Great Rift Valley of Kenya. Lake Magadi is the southernmost lake in the Kenyan Rift Valley, north of Tanzania's Lake Natron. The Rift Valley contains a chain of volcanoes, some of which are still active, and many other lakes such as the Turkana, Baringo, Bogoria and Nakuru. During the dry season Lake Magadi is 60% covered by soda and is known for its wading birds. During the rainy season, a thin layer of brine covers much of the saline pan, but this evaporates rapidly leaving a vast expanse of white salt that cracks to produce large polygons. The lake is recharged by saline hot springs that discharge into alkaline lagoons around the lake margins and is very rich in blue-green algae, which feed insects, small crustaceans and massive flocks of lesser flamingos (Phoenicoparrus minor). Altogether it forms a very peculiar mineral and colour-rich landscape. The lake is featured in film The Constant Gardener, which is based on the book of the same name by John le Carré although in the film the shots are supposed to be at Lake Turkana. Currently the area is inhabited by the cattle-herder Masai tribes, but the relics of many hominids have been found in the escarpments.

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.
