abstract：:Analysis of 262 transgenic mouse pedigrees suggests that about 30% of the mice produced by microinjection of plasmids into pronuclei are mosaic in the germline. This implies that in these lines integration of the foreign DNA occurred after the first round of chromosomal DNA replication. In mosaics resulting from delay...
