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.
Lateral Collateral Ligament (LCL) Tears. The lateral collateral ligament is a thin band of tissue running along the outside of the knee. It connects the thighbone (femur) to the fibula, which is the small bone of the lower leg that turns down the side of the knee and connects to the ankle. Like the medial collateral ligament, the lateral collateral ligament's main function is to keep the knee stable as it moves through its full arc of motion.
