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.
RFLP analysis is an outdated method for DNA fingerprinting. Mainly because you need lots of DNA to start with and crime scenes often do not leave that much DNA, and also because the information you get from RFLP is not as individually unique as current forensic methods.ou need to know this so you know how much DNA to use in the next step. 4. Using a set amount of DNA you extracted as template, and a STR multiplex kit, for example Power Plex from Promega or Identifiler from Life Technologies, amplify the STR loci on the template DNA using taq DNA polymerase.
