The traditional names of the rowan are those applied to the species Sorbus aucuparia, Sorbus torminalis (wild service-tree), and Sorbus domestica (true service-tree). The Latin name sorbus was borrowed into Old English as syrfe. The name service-tree for Sorbus domestica is derived from that name by folk etymology.
Restriction fragment length polymorphism. In molecular biology, restriction fragment length polymorphism, or RFLP, is a technique that exploits variations in homologous DNA sequences. It refers to a difference between samples of homologous DNA molecules from differing locations of restriction enzyme sites, and to a related laboratory technique by which these segments can be illustrated.
Anatomy. The lateral collateral ligament (LCL) is a one of the four major ligaments in the knee. The LCL is on the outside of the knee connecting the thighbone (femur) to the smaller bone in the lower leg (fibular). Its main function is to avoid varus stress across the knee (where the knee buckles outwards).
