In the Ventral Nerve Cord of the Drosophila Larva, Each

question 17

Essay

In the ventral nerve cord of the Drosophila larva, each neuroblast (neural stem cell) divides repeatedly, regenerating itself and generating a transient ganglion mother cell with each division (Figure Q7-4). Each ganglion mother cell then divides to produce two daughter cells. At the end of this process, a full neuroblast lineage is composed of two different types of neurons, A and B, in approximately equal numbers. Figure Q7-4
A. How might these two distinct types of neurons be generated?
B. What are some experiments that could be performed to test this hypothesis?
