| Abstract: | A general method is presented for stable transfer of genetic information to eukaryotic cells, utilizing metaphase chromosomes as the vehicle. Recent progress, current problems and large areas of uncertainty in this field are reviewed; particular consideration is given to frequency of transfer, size of the transgenome, evidence of cotransfer of linked genes and serial chromosome transfer. A reasonable model for chromosome transfer is considered with respect to the available information, and various descrepancies are noted. The utility of this method for fine structural mapping, cloning small regions of the eukaryotic genome and other potential applications are discussed. |
