Synthesis of DNA-DNA and DNA-RNA Duplexes | Genetics | Embryology

The study of genetic information carriers—DNA and RNA—depends to a large degree on the possibility of identifying sequences of these materials; that is, determining which sequences are similar or identical, and which are dissimilar. A complete chemical analysis of each molecule would be the most satisfactory method, but such an analysis, although possible, is very laborious, and it needs a [...]

Morphogenetic Gradients in the Egg Cytoplasm | Cleavage | Embryology

The cytoplasm of the egg, and particularly its cortex, starts the chain of reactions which eventually leads to the differentiation of parts of the embryo, it should not be assumed that the structure of the future embryo is rigidly determined by local differences in the cytoplasm of the egg. The local peculiarities of the egg cytoplasm are only some of [...]
