Multiple Choice
Which of the following is NOT true regarding vertebrate segmentation?
A) The presomitic mesoderm retreats tailward as new somites are generated.
B) The period of gene-expression oscillations in the presomitic mesoderm determines the size of each somite.
C) If feedback delays in the gene-expression oscillations are increased, somite size will consequently increase as well.
D) Notch-mediated lateral inhibition ensures that the segmentation clock is different in neighboring cells in the presomitic mesoderm.
