WebAug 11, 2009 · 2.1 Short string probes and K-means clustering. To probe an analyzed sequence for the presence of tandem repeats we use short strings (SS) no longer than the repeat length (see example in Fig. 2).For proteins, the size of SS was chosen equal to two because the longer SS were less efficient for detection of two-residue repeats and some … DNA sequences are linked together in a gene pool by gene conversion events. Insertion of an interspersed DNA element breaks this linkage, allowing independent evolution of a new gene. The interspersed repeat is an isolating mechanism enabling new genes to evolve without interference from the progenitor gene. Because insertion of an interspersed repeat is a saltatory event the evolution of the new gene will also be saltatory. Because speciation ultimately depends on the cr… WebIn cases where the Alu inserted into an older repeat, the parts on either side can be recognized as belonging to the same element.
