41. Mice, Drosophila and many other organisms only have one cyclin D protein. 42. Drosophila flies exhibit specific relationships between neurons and behavior.43. Axonal pathfinding and fasciculation behaviour in the embryonic ventral nerve cord of Drosophila . 44. It was later predicted and confirmed experimentally in Drosophila . 45. The Drosophila CNS is composed of two brain hemispheres and the ventral ganglion. 46. Individual genes in each complex correspond to specific members of the Drosophila genome. 47. Furthermore, miR-184 has multiple roles in Drosophila female germline development. 48. She continued to isolate and characterize nonhistone chromosomal proteins but started studying Drosophila . 49. Drosophila Commissureless ( Comm ) is a transmembrane protein expressed in commissural neurons.50. PiRNAs were first observed in Drosophila in 1990 ( Johnson, 2 ).
