PRODUCTION OF RECOMBINANT ORGANISMS

摘要

A method comprising: a) altering a chromosomal sequence of a donor nucleus of a donor cell by introducing a pair of single-stranded targeting polynucleotides, and a recombinase into said donor nucleus of said donor cell, wherein said pair of targeting polynucleotides are substantially complementary to each other and each comprising a homology clamp that substantially corresponds to or is substantially complementary to a predetermined DNA sequence of said nucleus; and, b) transplanting said nucleus into an oocyte to produce a recombinant zygote. A method of altering a nucleic acid sequence of a mitochondria or chloroplast of a cell comprising: introducing into a cell a pair of single-stranded targeting polynucleotides, and recombinase, wherein said pair of targeting polynucleotides are substantially complementary to each other, and each comprising a homology clamp that substantially corresponds to or is substantially complementary to a predetermined nucleic acid sequence of said mitochondria or chloroplast, whereby said sequence is altered.
