Students learn how to predict the shape of a molecule based on the electron dot diagram. Covalent Bonds: Students learn how to predict the shape of a molecule based on the electron dot diagram and to ...

Most cells in the body are polarized, showing some level of shape and functional asymmetry, such as apico–basal or front–back polarity. Tissues are formed from the coordinated integration of ...

Three sets of conserved polarity proteins — the partitioning defective (PAR), Scribble and Crumbs complexes — regulate polarization processes in many different cell types and organisms, including ...

The Feltri lab seeked to understand how cell-cell and cell-extracellular matrix interactions contribute to cell shape and polarity within a developing tissue. They applied these biological questions ...
