Understanding how morphogens promote three-dimensional patterning is an important issue in developmental biology. Recently, new insights have been gained into the mechanisms by which the Drosophila ...

Sticky spots on cell membranes hold onto the master regulator of cell polarity, helping to ensure that the regulatory protein accumulates in high enough concentrations to trigger cell polarity. Over ...

This paper seeks to identify the factors which have the greatest effect on gas diffusion rates into animal burrows, and in turn on the maximum size of burrowing animals which may rely on simple burrow ...

The American Biology Teacher, a nationally recognized journal, offers articles on recent advances in biology and life science, instructional activities for the classroom and laboratory, and ...

Light and electron microscopes allow us to see inside cells. Plant, animal and bacterial cells have smaller components each with a specific function. Enzymes - Edexcel Enzymes are biological catalysts ...
