2. DNA damage-binding protein - Wikipedia

   en.wikipedia.org/wiki/DNA_damage-binding_protein

   DNA damage-binding protein or UV-DDB [1] is a protein complex that is responsible for repair of UV-damaged DNA. [2] This complex is composed of two protein subunits, a large subunit DDB1 (p127) and a small subunit DDB2 (p48). When cells are exposed to UV radiation, DDB1 moves from the cytosol to the nucleus and binds to DDB2, thus forming the ...

3. UVB-induced apoptosis - Wikipedia

   en.wikipedia.org/wiki/UVB-induced_apoptosis

   Apoptosis is a physiological process, that promotes the active suicide of cells, resulting in an advantage, unlike necrosis which occurs from trauma. In the average human adult it is estimated that 50 to 70 billion cells die each day from apoptosis. One of the largest promoters of apoptosis is exposure to ultraviolet (UV) light.

4. Hypercomplex cell - Wikipedia

   en.wikipedia.org/wiki/Hypercomplex_cell

   A hypercomplex cell (currently called an end-stopped cell) is a type of visual processing neuron in the mammalian cerebral cortex.Initially discovered by David Hubel and Torsten Wiesel in 1965, hypercomplex cells are defined by the property of end-stopping, which is a decrease in firing strength with increasingly larger stimuli.

5. Complex cell - Wikipedia

   en.wikipedia.org/wiki/Complex_cell

   Complex cells receive inputs from a number of simple cells. Their receptive field is therefore a summation and integration of the receptive fields of many input simple cells, although some input is directly received from the LGN. [4] The manner through which simple cells are able to make up complex cells is not fully understood.

6. Vault (organelle) - Wikipedia

   en.wikipedia.org/wiki/Vault_(organelle)

   The vault or vault cytoplasmic ribonucleoprotein is a eukaryotic organelle (a structure in the cells of multicellular organisms) whose function is not yet fully understood. . Discovered and isolated by Nancy Kedersha and Leonard Rome in 1986, [2] vaults are cytoplasmic structures (outside the nucleus) which, when negative-stained and viewed under an electron microscope, resemble the arches of ...

7. Ultraviolet–visible spectroscopy - Wikipedia

   en.wikipedia.org/wiki/Ultraviolet–visible...

   A UV-Vis spectrophotometer is an analytical instrument that measures the amount of ultraviolet (UV) and visible light that is absorbed by a sample. It is a widely used technique in chemistry, biochemistry, and other fields, to identify and quantify compounds in a variety of samples.
