Figure 2

Giant LBCs from salamanders, isolated in a saline solution. A. The earliest image of a LBC isolated in a saline solution, from the newt Cynops (Triturus) pyrrhogaster. The homologous chromosomes are being stretched between microneedles. Reproduced from Duryee [6] with permission from the University of Pennsylvania Press. B. A pair of homologous LBCs from the newt Notophthalmus viridescens, isolated in a saline solution but not centrifuged. This image was taken by flash photography to stop the vigorous Brownian motion of the chromatin loops that extend laterally from the chromosome axis. Bars = 100 μm.
