Homologous recombination involves the alignment of similar sequences, a crossover between the aligned DNA strands, and breaking and repair of the . Also, methods are provided for introducing modifications into genomic exons by inserting introns into the genomic exons via homologous recombination such that a mature mRNA transcript produced from a genomic region of the genome comprising the genomic exon Exon
