The auxin receptor is composed of two proteins: the SCF complex component TIR1 and the repressor protein AUX/IAA. Ubiquitin moieties are first activated by E1 ligase and added to target proteins by E2 ligase.

In case of hotstart PCR, After the reaction mixture is prepared, primers can pair to the single-stranded regions in a nonspecific manner. 

A more attractive alternative is to cover the reaction mixture with a plug of inert wax and place the critical reagent on top of this plug.

Both genetic and physical maps provide information about the relative positions of and distances between genes. Genetic maps are based on rates of recombination and are measured in recombination frequencies (centiMorgans or map units).
