Chemistry of the Chick Embryo
Despite voluminous literature describing the chemical changes which accompany development of the chick embryo, there are few quantitative data on the occurrence of respiratory and glycolytic enzymes and coenzymes. Since these catalysts are concerned with reactions which may be available for the processes of growth and differentiation, more knowledge of their activities during the incubation per...
متن کاملThe Developing Chick Embryo
The RNA-P and DNA-P content of the nucleus and the RNA-P content of the whole cell of the livers of 8to 20-day chick embryos and of adult fowls have been determined. The DNA-P content of the liver nuclei was slightly higher in the 8and 10-day embryo than in all the other stages examined. A significant decrease in the RNA content of the cell occurred during embryonic development. The RNA content...

متن کاملCleavage in the chick embryo.
Chick embryos ranging from the stage of first cleavage to that of about 700 cells were removed from the oviduct and examined by transmission electron microscopy. Beneath the cell membrane is yolk-free cortical region containing microfilaments. Beneath this lies cytoplasm which contains yolk spheres which are graded in size, the dorsal ones being smaller than the ventral ones. The subgerminal pe...
