And the manner which produces the cell where heredity it rearranged from the true mycetocyte where be inherited rearrangement occurs

摘要

The present invention relates to a method for increasing genetic recombination frequency in a genomic DNA and a method for inducing genome rearrangement. Specifically, according to the present invention there are provided: the method for increasing genetic recombination frequency in a cell in which genetic recombination takes place at any sites in the genome, comprising causing a restriction enzyme to be expressed in the cell, inducing transient activation of the restriction enzyme, and then introducing 2 or more double strand cleavages into any genomic DNA of the cell, so as to increase the genetic recombination frequency; the method for inducing genome rearrangement through the use of the above method; and cells each prepared through the use of the above 2 methods.
