a Developmental genetics: 1. expression of differential gene function during early embryogenesis 

 and cytodifferentiation with an emphasis on those genes responsible for isozymes; 2. correlation 

 of lactate dehydrogenase gene homology with the specificity of the gene activating mechanisms 

 during development; 3. genetical, physical, and chemical analysis of the lactate dehydrogenase 

 isozymes unique to the differentiated nervous system; 4. biochemical genetics of isozymes, 

 especially lactate dehydrogenase; 5. asynchronous allele activation during embryogenesis of 

 interspecific and intergeneric hybrids. Micropterus dolomieui, M. salmoides and other spp. 

 (Centrarchidae, Teleostei) 



b Epigenetic and genetic control of protein synthesis during cytodifferentiation with emphasis on 

 the post-translational control of gene product (especially lactate dehydrogenase isozymes), 

 assembly and function. (Teleostei and other Vertebrata)
