The ability of proteins to locate specific target sequences or structures among a vast excess of nonspecific DNA is a fundamental property that affects virtually all aspects of biology. Despite this ...

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 ...

Part of Biology (Single Science) Living together - Food and ecosystems Diffusion is crucial in both single-celled and multi-celled organisms. In both single-celled organisms like prokaryotic bacteria ...
