  • 2017
  • Issue: 6
  • Volume: 47
O. Bamidele, M. De Donato, S. O. Peters, O. G. Omitogun & I. G. Imumorin Page: 813 - 821

Achaete-scute like-2 (ASCL2) gene is a maternally expressed gene that encodes a lineage-specific transcription factor that is essential for neurectoderm and trophectoderm development and is implicated in pre-natal and post-natal development in mammals. Using comparative genomics, various in silico sequence…
