analysis of temporal expression of mitochondrial genome during oogenesis using cDNA "back- 

 hybridisation". Xenopus laevis (Anura) 

 b Nucleocytoplasmic interactions during oogenesis: 1. formation of mitochondrial hybrids by 



microinjection of organelles from one species to another; 2. detection of hybrid mitochondrial 



populations by radioactive cRNA synthesised from purified mitochondrial DNAs and restriction 



endonuclease patterns; 3. analysis of nucleocytoplasmic transfer of macromolecules in "hybrids".
