| Description: (a) The nurse cells transport maternal effect gene products, such as bicoid mRNA, into the anterior end of the developing oocyte. (b) Staining of bicoid mRNA in an oocyte before fertilization. The bicoid mRNA is trapped near the anterior end. (c) Staining of Bicoid protein after fertilization. The Bicoid protein forms a gradient, with its highest concentration near the anterior end.
