Sunburn is a reaction to DNA damage caused by UV light. An inflorescence in which the flower stalks (pedicels) radiate from a common point. The hoselike structure connecting the placenta to the embryo or fetus; contains the umbilical artery and vein. The navel (or umbilicus) marks the point of its former attachment. MOLECULAR STRUCTURE undulipodium (pl undulipodia) /ƏN-dyə-lə-PODE-ee-əm/ n. The muscular reservoir for urine, which it collects from the ureters, and discharges from the body through the urethra. The waste fluid produced by the kidneys and stored in the urinary bladder prior to excretion. Of or pertaining to the reproductive and urinary organs. The study and treatment of disorders of the urogenital organs. The genus to which the brown bear, Ursus arctos, and the cave bear, Ursus spelaeus belong.
UV-B (wavelength 3200 Å-2800 Å) and UV-C (wavelength 2800 Å-1000 Å) radiation both damage DNA and are therefore detrimental to most organisms.

Tiny RNA plant pathogens, usually about 300 nucleotides long; thousands of times smaller than the smallest virus. Inside the infected cell, the virus uses the translational system of the host to produce progeny virus. They only carry enough genetic material to encode a few proteins.
