- Discuss Concepts Experimentally, it is possible to divide an amphibian egg so that the gray crescent is wholly within one of the two cells formed. If the two cells are separated, only the cell with the gray crescent will form an embryo with a long axis, notochord, nerve cord, and back musculature. The other forms a shapeless mass of immature gut and blood cells. Propose an explanation for these outcomes.arrow_forwardExplain how you would compare the expression of a gene in a cancer cell and a normal cell using qPCR, a DNA chip, and RNA-seq analysis.arrow_forwardDivision & Differentiation 10 What is the role of centrosomes during cell division?
