The stereo typed pattern of the PNS results from the pattern in which neural precursors arise from the ectoderm during development Ghysen and DamblyChaudire 1989 Neural precursor formation is an important model for the processes of cell spec i64257c 624 . - Developmental Genetics. Lecture . #4 – . Gastrulation. . Movements. . GASTRULATION is a complex series of cell movements that:. --rearranges cells, giving them new neighbors. --results in the formation of 3 GERM LAYERS that will form the subsequent embryo: ectoderm, endoderm and mesoderm. Drosophila singed were named for their gnarled bristle phenotype but severe alleles are also female sterile. Recently, singed protein was shown to have 35 % peptide identity with echinoderm fascin.

Crystal growth problem Is a classical example of a phase transformation from the liquid phase to the solid phase via heat transfer, for example the formation of snowflakes.
