Gene Activity during Gastrulation of Embryos | Embryology
In this article we will discuss about the gene activity during gastrulation period of embryos. Fragments of sea urchin eggs not containing the nucleus may be treated with agents who cause parthenogenetic activation of the egg (viz., hypertonic seawater). It has been found that the non-nucleated fragments begin to cleave and may reach the morula stage. The animals (embryos), however, [...]
