In particular, she wants to study why proteins can take on different conformations in different types of cells, or cells from people with different genetic backgrounds. (wi.mit.edu)
A variety of different conformations were observed, and as de Gennes notes, two chains can exhibit very different behavior even when put under the same conditions of stretching. (science.sciencemag.org)
Moreover, they may have diverged from a common ancestor about 10 million years ago, when the Amazon River basin had a quite different conformation compared with the current one. (sciencedaily.com)
