Targeting and enhancing RNA-RNA recombination

摘要

A construct formed from a first RNA molecule carrying an antisense insert complementary to a nucleotide sequence in a second target RNA molecule is used to direct crossovers between the first and second RNAs at or near the site of hybridization. The incidence of recombination and the location of recombinant junctions depends on the structure of the recombining RNA molecules and on the stability of the heteroduplex region. The RNA-RNA construct may be provided in double stranded DNA form. The DNA form may be inserted into a vector and used to transform or transfect a host.
