Genetic instructions from mom set the pattern for embryonic development

Micrograph of a zebrafish organ called the Kupffer's vesicle

By the Department of Molecular Biology A new study indicates an essential role for a maternally inherited gene in embryonic development. The study found that zebrafish that failed to inherit specific genetic instructions from mom developed fatal defects earlier in development, even if the fish could make their own version of the gene. The study … Continue reading Genetic instructions from mom set the pattern for embryonic development

Come together: Nucleolus forms via combination of active and passive processes

https://youtu.be/DxYDy1fQlV8?rel=0 Movie caption: Researchers at Princeton studied the temperature dependence of the formation of the nucleolus, a cellular organelle. The movie shows the nuclei of intact fly cells as they are subjected to temperature changes in the surrounding fluid. As the temperature is shifted from low to high, the spontaneously assembled proteins dissolve, as can … Continue reading Come together: Nucleolus forms via combination of active and passive processes
